# Linguist
-We use this library at GitHub to detect blob languages, highlight code, ignore binary files, suppress generated files in diffs and generate language breakdown graphs.
+We use this library at GitHub to detect blob languages, highlight code, ignore binary files, suppress generated files in diffs, and generate language breakdown graphs.
## Features
### Language detection
-Linguist defines the list of all languages known to GitHub in a [yaml file](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml). In order for a file to be highlighted, a language and lexer must be defined there.
+Linguist defines a list of all languages known to GitHub in a [yaml file](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml). In order for a file to be highlighted, a language and a lexer must be defined there.
-Most languages are detected by their file extension. This is the fastest and most common situation.
-
-For disambiguating between files with common extensions, we use a [Bayesian classifier](https://github.com/github/linguist/blob/master/lib/linguist/classifier.rb). For an example, this helps us tell the difference between `.h` files which could be either C, C++, or Obj-C.
-
-In the actual GitHub app we deal with `Grit::Blob` objects. For testing, there is a simple `FileBlob` API.
+Most languages are detected by their file extension. For disambiguating between files with common extensions, we first apply some common-sense heuristics to pick out obvious languages. After that, we use a
+[statistical
+classifier](https://github.com/github/linguist/blob/master/lib/linguist/classifier.rb).
+This process can help us tell the difference between, for example, `.h` files which could be either C, C++, or Obj-C.

The actual syntax highlighting is handled by our Pygments wrapper, [pygments.rb](https://github.com/tmm1/pygments.rb). It also provides a [Lexer abstraction](https://github.com/tmm1/pygments.rb/blob/master/lib/pygments/lexer.rb) that determines which highlighter should be used on a file.
-We typically run on a pre-release version of Pygments, [pygments.rb](https://github.com/tmm1/pygments.rb), to get early access to new lexers. The [languages.yml](https://github.com/github/linguist/blob/master/lib/linguist/languages.yml) file is a dump of the lexers we have available on our server.

### Stats
-The Language Graph you see on every repository is built by aggregating the languages of each file in that repository.
-The top language in the graph determines the project's primary language. Collectively, these stats make up the [Top Languages](https://github.com/languages) page.

+
+
+
+
+Effective ATS: Dining Philosophers
+
+
+In this article, I present an implementation of a slight variant of the
+famous problem of 5-Dining-Philosophers by Dijkstra that makes simple but
+convincing use of linear types.
+
+
+The Original Problem
+
+
+There are five philosophers sitting around a table and there are also 5
+forks placed on the table such that each fork is located between the left
+hand of a philosopher and the right hand of another philosopher. Each
+philosopher does the following routine repeatedly: thinking and dining. In
+order to dine, a philosopher needs to first acquire two forks: one located
+on his left-hand side and the other on his right-hand side. After
+finishing dining, a philosopher puts the two acquired forks onto the table:
+one on his left-hand side and the other on his right-hand side.
+
+
+A Variant of the Original Problem
+
+
+The following twist is added to the original version:
+
+
+
+After a fork is used, it becomes a "dirty" fork and needs to be put in a
+tray for dirty forks. There is a cleaner who cleans dirty forks and then
+puts them back on the table.
+
+
+Channels for Communication
+
+
+A channel is just a shared queue of fixed capacity. The following two
+functions are for inserting an element into and taking an element out of a
+given channel:
+
+
+#pats2xhtml_sats("\
+fun{a:vt0p} channel_insert (channel (a), a): void
+fun{a:vt0p} channel_takeout (chan: channel (a)): (a)
+")
+
+If [channel_insert] is called on a channel that is full, then the caller is
+blocked until an element is taken out of the channel. If [channel_takeout]
+is called on a channel that is empty, then the caller is blocked until an
+element is inserted into the channel.
+
+
+A Channel for Each Fork
+
+
+Forks are resources given a linear type. Each fork is initially stored in a
+channel, which can be obtained by calling the following function:
+
+
+#pats2xhtml_sats("\
+fun fork_changet (n: nphil): channel(fork)
+")
+
+where the type [nphil] is defined to be [natLt(5)] (for natural numbers
+less than 5). The channels for storing forks are chosen to be of capacity
+2. The reason that channels of capacity 2 are chosen to store at most one
+element (in each of them) is to guarantee that these channels can never be
+full (so that there is no attempt made to send signals to awake callers
+supposedly being blocked due to channels being full).
+
+
+
+A Channel for the Fork Tray
+
+
+A tray for storing "dirty" forks is also a channel, which can be obtained
+by calling the following function:
+
+
+#pats2xhtml_sats("\
+fun forktray_changet ((*void*)): channel(fork)
+")
+
+The capacity chosen for the channel is 6 (instead of 5) so that it can
+never become full (as there are only 5 forks in total).
+
+
+Philosopher Loop
+
+
+Each philosopher is implemented as a loop:
+
+
+#pats2xhtml_dats('\
+implement
+phil_loop (n) = let
+//
+val () = phil_think (n)
+//
+val nl = phil_left (n) // = n
+val nr = phil_right (n) // = (n+1) % 5
+//
+val ch_lfork = fork_changet (nl)
+val ch_rfork = fork_changet (nr)
+//
+val lf = channel_takeout (ch_lfork)
+val () = println! ("phil_loop(", n, ") picks left fork")
+//
+val () = randsleep (2) // sleep up to 2 seconds
+//
+val rf = channel_takeout (ch_rfork)
+val () = println! ("phil_loop(", n, ") picks right fork")
+//

+
+
+Fork Cleaner Loop
+
+
+A cleaner is implemented as a loop:
+
+
+#pats2xhtml_dats('\
+implement
+cleaner_loop () = let
+//
+val ch = forktray_changet ()
+val f0 = channel_takeout (ch) // [f0] is dirty
+//
+val () = cleaner_wash (f0) // washes dirty [f0]
+val () = cleaner_return (f0) // puts back cleaned [f0]
+//
+in
+ cleaner_loop ()
+end // end of [cleaner_loop]
+')
+
+The function [cleaner_return] first finds out the number of a given fork
+and then uses the number to locate the channel for storing the fork. Its
+actual implementation is given as follows:
+
+
+#pats2xhtml_dats('\
+implement
+cleaner_return (f) =
+{
+ val n = fork_get_num (f)
+ val ch = fork_changet (n)
+ val () = channel_insert (ch, f)
+}
+')
+
+It should now be straighforward to follow the code for [cleaner_loop].
+
+
+Testing
+
+
+The entire code of this implementation is stored in the following files:
+
+
+DiningPhil2.sats
+DiningPhil2.dats
+DiningPhil2_fork.dats
+DiningPhil2_thread.dats
+
+
+There is also a Makefile available for compiling the ATS source code into
+an excutable for testing. One should be able to encounter a deadlock after
+running the simulation for a while.

+ * Model of views in object-oriented programming.

+ * Two object references, called the view and the backing,
+ * are related by a view mechanism when changes to the
+ * backing are automatically propagated to the view. Note
+ * that the state of a view need not be a projection of the
+ * state of the backing; the keySet method of Map, for
+ * example, produces two view relationships, and for the
+ * one in which the map is modified by changes to the key
+ * set, the value of the new map cannot be determined from
+ * the key set. Note that in the iterator view mechanism,
+ * the iterator is by this definition the backing object,
+ * since changes are propagated from iterator to collection
+ * and not vice versa. Oddly, a reference may be a view of
+ * more than one backing: there can be two iterators on the
+ * same collection, eg. A reference cannot be a view under
+ * more than one view type.
+ *
+ * A reference is made dirty when it is a backing for a view
+ * with which it is no longer related by the view invariant.
+ * This usually happens when a view is modified, either
+ * directly or via another backing. For example, changing a
+ * collection directly when it has an iterator invalidates
+ * it, as does changing the collection through one iterator
+ * when there are others.
+ *
+ * More work is needed if we want to model more closely the
+ * failure of an iterator when its collection is invalidated.
+ *
+ * As a terminological convention, when there are two
+ * complementary view relationships, we will give them types
+ * t and t'. For example, KeySetView propagates from map to
+ * set, and KeySetView' propagates from set to map.

+// C and C++ support for Broadcom BCM 2835 as used in Raspberry Pi
+//
+// Author: Mike McCauley
+// Copyright (C) 2011-2013 Mike McCauley

+//
+/// \mainpage C library for Broadcom BCM 2835 as used in Raspberry Pi
+///
+/// This is a C library for Raspberry Pi (RPi). It provides access to
+/// GPIO and other IO functions on the Broadcom BCM 2835 chip,
+/// allowing access to the GPIO pins on the
+/// 26 pin IDE plug on the RPi board so you can control and interface with various external devices.
+///
+/// It provides functions for reading digital inputs and setting digital outputs, using SPI and I2C,
+/// and for accessing the system timers.
+/// Pin event detection is supported by polling (interrupts are not supported).
+///
+/// It is C++ compatible, and installs as a header file and non-shared library on
+/// any Linux-based distro (but clearly is no use except on Raspberry Pi or another board with
+/// BCM 2835).
+///
+/// The version of the package that this documentation refers to can be downloaded
+/// from http://www.airspayce.com/mikem/bcm2835/bcm2835-1.26.tar.gz
+/// You can find the latest version at http://www.airspayce.com/mikem/bcm2835
+///
+/// Several example programs are provided.
+///
+/// Based on data in http://elinux.org/RPi_Low-level_peripherals and
+/// http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf
+/// and http://www.scribd.com/doc/101830961/GPIO-Pads-Control2
+///
+/// You can also find online help and discussion at http://groups.google.com/group/bcm2835
+/// Please use that group for all questions and discussions on this topic.
+/// Do not contact the author directly, unless it is to discuss commercial licensing.
+///
+/// Tested on debian6-19-04-2012, 2012-07-15-wheezy-raspbian and Occidentalisv01
+/// CAUTION: it has been observed that when detect enables such as bcm2835_gpio_len()
+/// are used and the pin is pulled LOW
+/// it can cause temporary hangs on 2012-07-15-wheezy-raspbian and Occidentalisv01.
+/// Reason for this is not yet determined, but suspect that an interrupt handler is
+/// hitting a hard loop on those OSs.
+/// If you must use bcm2835_gpio_len() and friends, make sure you disable the pins with
+/// bcm2835_gpio_cler_len() and friends after use.
+///
+/// \par Installation
+///
+/// This library consists of a single non-shared library and header file, which will be
+/// installed in the usual places by make install
+///
+/// \code
+/// # download the latest version of the library, say bcm2835-1.xx.tar.gz, then:
+/// tar zxvf bcm2835-1.xx.tar.gz
+/// cd bcm2835-1.xx
+/// ./configure
+/// make
+/// sudo make check
+/// sudo make install
+/// \endcode
+///
+/// \par Physical Addresses
+///
+/// The functions bcm2835_peri_read(), bcm2835_peri_write() and bcm2835_peri_set_bits()
+/// are low level peripheral register access functions. They are designed to use
+/// physical addresses as described in section 1.2.3 ARM physical addresses
+/// of the BCM2835 ARM Peripherals manual.
+/// Physical addresses range from 0x20000000 to 0x20FFFFFF for peripherals. The bus
+/// addresses for peripherals are set up to map onto the peripheral bus address range starting at
+/// 0x7E000000. Thus a peripheral advertised in the manual at bus address 0x7Ennnnnn is available at
+/// physical address 0x20nnnnnn.
+///
+/// The base address of the various peripheral registers are available with the following
+/// externals:
+/// bcm2835_gpio
+/// bcm2835_pwm
+/// bcm2835_clk
+/// bcm2835_pads
+/// bcm2835_spio0
+/// bcm2835_st
+/// bcm2835_bsc0
+/// bcm2835_bsc1
+///
+/// \par Pin Numbering
+///
+/// The GPIO pin numbering as used by RPi is different to and inconsistent with the underlying
+/// BCM 2835 chip pin numbering. http://elinux.org/RPi_BCM2835_GPIOs
+///
+/// RPi has a 26 pin IDE header that provides access to some of the GPIO pins on the BCM 2835,
+/// as well as power and ground pins. Not all GPIO pins on the BCM 2835 are available on the
+/// IDE header.
+///
+/// RPi Version 2 also has a P5 connector with 4 GPIO pins, 5V, 3.3V and Gnd.
+///
+/// The functions in this library are designed to be passed the BCM 2835 GPIO pin number and _not_
+/// the RPi pin number. There are symbolic definitions for each of the available pins
+/// that you should use for convenience. See \ref RPiGPIOPin.
+///
+/// \par SPI Pins
+///
+/// The bcm2835_spi_* functions allow you to control the BCM 2835 SPI0 interface,
+/// allowing you to send and received data by SPI (Serial Peripheral Interface).
+/// For more information about SPI, see http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus
+///
+/// When bcm2835_spi_begin() is called it changes the bahaviour of the SPI interface pins from their
+/// default GPIO behaviour in order to support SPI. While SPI is in use, you will not be able
+/// to control the state of the SPI pins through the usual bcm2835_spi_gpio_write().
+/// When bcm2835_spi_end() is called, the SPI pins will all revert to inputs, and can then be
+/// configured and controled with the usual bcm2835_gpio_* calls.
+///
+/// The Raspberry Pi GPIO pins used for SPI are:
+///
+/// - P1-19 (MOSI)
+/// - P1-21 (MISO)
+/// - P1-23 (CLK)
+/// - P1-24 (CE0)
+/// - P1-26 (CE1)
+///
+/// \par I2C Pins
+///
+/// The bcm2835_i2c_* functions allow you to control the BCM 2835 BSC interface,
+/// allowing you to send and received data by I2C ("eye-squared cee"; generically referred to as "two-wire interface") .
+/// For more information about I?C, see http://en.wikipedia.org/wiki/I%C2%B2C
+///
+/// The Raspberry Pi V2 GPIO pins used for I2C are:
+///
+/// - P1-03 (SDA)
+/// - P1-05 (SLC)
+///
+/// \par Real Time performance constraints
+///
+/// The bcm2835 is a library for user programs (i.e. they run in 'userland').
+/// Such programs are not part of the kernel and are usually
+/// subject to paging and swapping by the kernel while it does other things besides running your program.
+/// This means that you should not expect to get real-time performance or
+/// real-time timing constraints from such programs. In particular, there is no guarantee that the
+/// bcm2835_delay() and bcm2835_delayMicroseconds() will return after exactly the time requested.
+/// In fact, depending on other activity on the host, IO etc, you might get significantly longer delay times
+/// than the one you asked for. So please dont expect to get exactly the time delay you request.
+///
+/// Arjan reports that you can prevent swapping on Linux with the following code fragment:
+///
+/// \code
+/// struct sched_param sp;
+/// memset(&sp, 0, sizeof(sp));
+/// sp.sched_priority = sched_get_priority_max(SCHED_FIFO);
+/// sched_setscheduler(0, SCHED_FIFO, &sp);
+/// mlockall(MCL_CURRENT | MCL_FUTURE);
+/// \endcode
+///
+/// \par Open Source Licensing GPL V2
+///
+/// This is the appropriate option if you want to share the source code of your
+/// application with everyone you distribute it to, and you also want to give them
+/// the right to share who uses it. If you wish to use this software under Open
+/// Source Licensing, you must contribute all your source code to the open source
+/// community in accordance with the GPL Version 2 when your application is
+/// distributed. See http://www.gnu.org/copyleft/gpl.html and COPYING
+///
+/// \par Acknowledgements
+///
+/// Some of this code has been inspired by Dom and Gert.
+/// The I2C code has been inspired by Alan Barr.
+///
+/// \par Revision History
+///
+/// \version 1.0 Initial release
+/// \version 1.1 Minor bug fixes
+/// \version 1.2 Added support for SPI
+/// \version 1.3 Added bcm2835_spi_transfern()
+/// \version 1.4 Fixed a problem that prevented SPI CE1 being used. Reported by David Robinson.
+/// \version 1.5 Added bcm2835_close() to deinit the library. Suggested by C?sar Ortiz
+/// \version 1.6 Document testing on 2012-07-15-wheezy-raspbian and Occidentalisv01
+/// Functions bcm2835_gpio_ren(), bcm2835_gpio_fen(), bcm2835_gpio_hen()
+/// bcm2835_gpio_len(), bcm2835_gpio_aren() and bcm2835_gpio_afen() now
+/// changes only the pin specified. Other pins that were already previously
+/// enabled stay enabled.
+/// Added bcm2835_gpio_clr_ren(), bcm2835_gpio_clr_fen(), bcm2835_gpio_clr_hen()
+/// bcm2835_gpio_clr_len(), bcm2835_gpio_clr_aren(), bcm2835_gpio_clr_afen()
+/// to clear the enable for individual pins, suggested by Andreas Sundstrom.
+/// \version 1.7 Added bcm2835_spi_transfernb to support different buffers for read and write.
+/// \version 1.8 Improvements to read barrier, as suggested by maddin.
+/// \version 1.9 Improvements contributed by mikew:
+/// I noticed that it was mallocing memory for the mmaps on /dev/mem.
+/// It's not necessary to do that, you can just mmap the file directly,
+/// so I've removed the mallocs (and frees).
+/// I've also modified delayMicroseconds() to use nanosleep() for long waits,
+/// and a busy wait on a high resolution timer for the rest. This is because
+/// I've found that calling nanosleep() takes at least 100-200 us.
+/// You need to link using '-lrt' using this version.
+/// I've added some unsigned casts to the debug prints to silence compiler
+/// warnings I was getting, fixed some typos, and changed the value of
+/// BCM2835_PAD_HYSTERESIS_ENABLED to 0x08 as per Gert van Loo's doc at
+/// http://www.scribd.com/doc/101830961/GPIO-Pads-Control2
+/// Also added a define for the passwrd value that Gert says is needed to
+/// change pad control settings.
+/// \version 1.10 Changed the names of the delay functions to bcm2835_delay()
+/// and bcm2835_delayMicroseconds() to prevent collisions with wiringPi.
+/// Macros to map delay()-> bcm2835_delay() and
+/// Macros to map delayMicroseconds()-> bcm2835_delayMicroseconds(), which
+/// can be disabled by defining BCM2835_NO_DELAY_COMPATIBILITY
+/// \version 1.11 Fixed incorrect link to download file
+/// \version 1.12 New GPIO pin definitions for RPi version 2 (which has a different GPIO mapping)
+/// \version 1.13 New GPIO pin definitions for RPi version 2 plug P5
+/// Hardware base pointers are now available (after initialisation) externally as bcm2835_gpio
+/// bcm2835_pwm bcm2835_clk bcm2835_pads bcm2835_spi0.
+/// \version 1.14 Now compiles even if CLOCK_MONOTONIC_RAW is not available, uses CLOCK_MONOTONIC instead.
+/// Fixed errors in documentation of SPI divider frequencies based on 250MHz clock.
+/// Reported by Ben Simpson.
+/// \version 1.15 Added bcm2835_close() to end of examples as suggested by Mark Wolfe.
+/// \version 1.16 Added bcm2835_gpio_set_multi, bcm2835_gpio_clr_multi and bcm2835_gpio_write_multi
+/// to allow a mask of pins to be set all at once. Requested by Sebastian Loncar.
+/// \version 1.17 Added bcm2835_gpio_write_mask. Requested by Sebastian Loncar.
+/// \version 1.18 Added bcm2835_i2c_* functions. Changes to bcm2835_delayMicroseconds:
+/// now uses the RPi system timer counter, instead of clock_gettime, for improved accuracy.
+/// No need to link with -lrt now. Contributed by Arjan van Vught.
+/// \version 1.19 Removed inlines added by previous patch since they don't seem to work everywhere.
+/// Reported by olly.
+/// \version 1.20 Patch from Mark Dootson to close /dev/mem after access to the peripherals has been granted.
+/// \version 1.21 delayMicroseconds is now not susceptible to 32 bit timer overruns.
+/// Patch courtesy Jeremy Mortis.
+/// \version 1.22 Fixed incorrect definition of BCM2835_GPFEN0 which broke the ability to set
+/// falling edge events. Reported by Mark Dootson.
+/// \version 1.23 Added bcm2835_i2c_set_baudrate and bcm2835_i2c_read_register_rs.
+/// Improvements to bcm2835_i2c_read and bcm2835_i2c_write functions
+/// to fix ocasional reads not completing. Patched by Mark Dootson.
+/// \version 1.24 Mark Dootson p[atched a problem with his previously submitted code
+/// under high load from other processes.
+/// \version 1.25 Updated author and distribution location details to airspayce.com
+/// \version 1.26 Added missing unmapmem for pads in bcm2835_close to prevent a memory leak.

+FUNCTION: CONSULTA
+
+COMMENTS:
+CONSULTA receives a list of hypothesis (variable ), and returns
+a list of binding lists (each binding list being a solution).
+
+EXAMPLES:
+hypotheses is:
+((brothers ?x ?y) (neighbours juan ?x)).
+
+That is, we are searching the brothers of the possible neighbors of Juan.
+
+The function can return in this case:
+
+(((?x . sergio) (?y . javier)) ((?x . julian) (?y . mario)) ((?x . julian) (?y . pedro))).
+That is, the neighbors of Juan (Sergio and Julian) have 3 brothers in total(Javier, Mario, Pedro)

+It tries (in the following order) to:
+- Answer the query from *fact-list*
+- Answer the query from the rules in *rule-list*
+- Ask the user
+
+The function returns a list of solutions (list of binding lists).
+
+EXAMPLES:
+If hypothesis is (brothers ?x ?y)
+and the function returns:
+(((?x . sergio) (?y . javier)) ((?x . julian) (?y . maria)) ((?x . alberto) (?y . pedro))).
+
+Means that Sergio and Javier and brothers, Julian and Mario are brothers, and Alberto and Pedro are brothers.

+#! @Description
+#! This is the main function of the &AutoDoc; package. It can perform
+#! any combination of the following three tasks:
+#!
+#! -
+#! It can (re)generate a scaffold for your package manual.
+#! That is, it can produce two XML files in &GAPDoc; format to be used as part
+#! of your manual: First, a file named
doc/PACKAGENAME.xml
+#! (with your package's name substituted) which is used as
+#! main file for the package manual, i.e. this file sets the
+#! XML DOCTYPE and defines various XML entities, includes
+#! other XML files (both those generated by &AutoDoc; as well
+#! as additional files created by other means), tells &GAPDoc;
+#! to generate a table of content and an index, and more.
+#! Secondly, it creates a file doc/title.xml containing a title
+#! page for your documentation, with information about your package
+#! (name, description, version), its authors and more, based
+#! on the data in your PackageInfo.g .
+#!
+#! -
+#! It can scan your package for &AutoDoc; based documentation (by using &AutoDoc;
+#! tags and the Autodoc command.
+#! This will
+#! produce further XML files to be used as part of the package manual.
+#!
+#! -
+#! It can use &GAPDoc; to generate PDF, text and HTML (with
+#! MathJaX enabled) documentation from the &GAPDoc; XML files it
+#! generated as well as additional such files provided by you. For
+#! this, it invokes
+#! to convert the XML sources, and it also instructs &GAPDoc; to copy
+#! supplementary files (such as CSS style files) into your doc directory
+#! (see ).
+#!
+#!
+#! For more information and some examples, please refer to Chapter .
+#!
+#! The parameters have the following meanings:
+#!
+#!
+#! package_name
+#! -
+#! The name of the package whose documentation should be(re)generated.
+#!
+#!
+#!
+#! option_record
+#! -
+#! option_record can be a record with some additional options.
+#! The following are currently supported:
+#!
+#! dir
+#! -
+#! This should be a string containing a (relative) path or a
+#! Directory() object specifying where the package documentation
+#! (i.e. the &GAPDoc; XML files) are stored.
+#!
+#! Default value: "doc/" .
+#!
+#! scaffold
+#! -
+#! This controls whether and how to generate scaffold XML files
+#! for the main and title page of the package's documentation.
+#!
+#! The value should be either
true , false or a
+#! record. If it is a record or true (the latter is
+#! equivalent to specifying an empty record), then this feature is
+#! enabled. It is also enabled if opt.scaffold is missing but the
+#! package's info record in PackageInfo.g has an AutoDoc entry.
+#! In all other cases (in particular if opt.scaffold is
+#! false ), scaffolding is disabled.
+#!
+#!
+#! If opt.scaffold is a record, it may contain the following entries.
+#!
+#### TODO: mention merging with PackageInfo.AutoDoc!
+#!
+#!
+#! includes
+#! -
+#! A list of XML files to be included in the body of the main XML file.
+#! If you specify this list and also are using &AutoDoc; to document
+#! your operations with &AutoDoc; comments,
+#! you can add
AutoDocMainFile.xml to this list
+#! to control at which point the documentation produced by &AutoDoc;
+#! is inserted. If you do not do this, it will be added after the last
+#! of your own XML files.
+#!
+#!
+#! appendix
+#! -
+#! This entry is similar to opt.scaffold.includes but is used
+#! to specify files to include after the main body of the manual,
+#! i.e. typically appendices.
+#!
+#!
+#! bib
+#! -
+#! The name of a bibliography file, in Bibtex or XML format.
+#! If this key is not set, but there is a file
doc/PACKAGENAME.bib
+#! then it is assumed that you want to use this as your bibliography.
+#!
+#!
+#### TODO: The 'entities' param is a bit strange. We should probably change it to be a bit more
+#### general, as one might want to define other entities... For now, we do not document it
+#### to leave us the choice of revising how it works.
+####
+#### entities
+#### -
+#### A list of package names or other entities which are used to define corresponding XML entities.
+#### For example, if set to a list containing the string
SomePackage
,
+#### then the following is added to the XML preamble:
+#### SomePackage'>]]>
+#### This allows you to write &SomePackage;
in your documentation
+#### to reference that package. If another type of entity is desired, one can simply add,
+#### instead of a string, add a two entry list a to the list. It will be handled as
+#### a[ 2 ]
'>]]>,
+#### so please be careful.
+####
+#!
+#! TitlePage
+#! -
+#! A record whose entries are used to embellish the generated titlepage
+#! for the package manual with extra information, such as a copyright
+#! statement or acknowledgments. To this end, the names of the record
+#! components are used as XML element names, and the values of the
+#! components are outputted as content of these XML elements. For
+#! example, you could pass the following record to set a custom
+#! acknowledgements text:
+#!
+#! For a list of valid entries in the titlepage, please refer to the
+#! &GAPDoc; manual, specifically section
+#! and following.
+#!
+#! document_class
+#! -
+#! Sets the document class of the resulting pdf. The value can either be a string
+#! which has to be the name of the new document class, a list containing this string, or
+#! a list of two strings. Then the first one has to be the document class name, the second one
+#! the option string ( contained in [ ] ) in LaTeX.
+#!
+#! latex_header_file
+#! -
+#! Replaces the standard header from &GAPDoc; completely with the header in this LaTeX file.
+#! Please be careful here, and look at GAPDoc's latexheader.tex file for an example.
+#!
+#! gapdoc_latex_options
+#! -
+#! Must be a record with entries which can be understood by SetGapDocLaTeXOptions. Each entry can be a string, which
+#! will be given to &GAPDoc; directly, or a list containing of two entries: The first one must be the string "file",
+#! the second one a filename. This file will be read and then its content is passed to &GAPDoc; as option with the name
+#! of the entry.
+#!
+#!
+#!
+#!
+#!
+#!
+#! autodoc
+#! -
+#! This controls whether and how to generate addition XML documentation files
+#! by scanning for &AutoDoc; documentation comments.
+#!
+#! The value should be either
true , false or a
+#! record. If it is a record or true (the latter is
+#! equivalent to specifying an empty record), then this feature is
+#! enabled. It is also enabled if opt.autodoc is missing but the
+#! package depends (directly) on the &AutoDoc; package.
+#! In all other cases (in particular if opt.autodoc is
+#! false ), this feature is disabled.
+#!
+#!
+#! If opt.autodoc is a record, it may contain the following entries.
+#!
+#!
+#!
+#! files
+#! -
+#! A list of files (given by paths relative to the package directory)
+#! to be scanned for &AutoDoc; documentation comments.
+#! Usually it is more convenient to use autodoc.scan_dirs, see below.
+#!
+#!
+#! scan_dirs
+#! -
+#! A list of subdirectories of the package directory (given as relative paths)
+#! which &AutoDoc; then scans for .gi, .gd and .g files; all of these files
+#! are then scanned for &AutoDoc; documentation comments.
+#!
+#! Default value: [ "gap", "lib", "examples", "examples/doc" ] .
+#!
+#!
+#! level
+#! -
+#! This defines the level of the created documentation. The default value is 0.
+#! When parts of the manual are declared with a higher value
+#! they will not be printed into the manual.
+#!
+#!
+#### TODO: Document section_intros later on.
+#### However, note that thanks to the new AutoDoc comment syntax, the only remaining
+#### use for this seems to be the ability to specify the order of chapters and
+#### sections.
+#### section_intros
+#### -
+#### TODO.
+####
+#!
+#!
+#!
+#!
+#!
+#! gapdoc
+#! -
+#! This controls whether and how to invoke &GAPDoc; to create HTML, PDF and text
+#! files from your various XML files.
+#!
+#! The value should be either
true , false or a
+#! record. If it is a record or true (the latter is
+#! equivalent to specifying an empty record), then this feature is
+#! enabled. It is also enabled if opt.gapdoc is missing.
+#! In all other cases (in particular if opt.gapdoc is
+#! false ), this feature is disabled.
+#!
+#!
+#! If opt.gapdoc is a record, it may contain the following entries.
+#!
+#!
+#!
+#!
+#### Note: 'main' is strictly speaking also used for the scaffold.
+#### However, if one uses the scaffolding mechanism, then it is not
+#### really necessary to specify a custom name for the main XML file.
+#### Thus, the purpose of this parameter is to cater for packages
+#### that have existing documentation using a different XML name,
+#### and which do not wish to use scaffolding.
+####
+#### This explain why we only allow specifying gapdoc.main.
+#### The scaffolding code will still honor it, though, just in case.
+#! main
+#! -
+#! The name of the main XML file of the package manual.
+#! This exists primarily to support packages with existing manual
+#! which use a filename here which differs from the default.
+#! In particular, specifying this is unnecessary when using scaffolding.
+#!
+#! Default value: PACKAGENAME.xml .
+#!
+#!
+#! files
+#! -
+#! A list of files (given by paths relative to the package directory)
+#! to be scanned for &GAPDoc; documentation comments.
+#! Usually it is more convenient to use gapdoc.scan_dirs, see below.
+#!
+#!
+#! scan_dirs
+#! -
+#! A list of subdirectories of the package directory (given as relative paths)
+#! which &AutoDoc; then scans for .gi, .gd and .g files; all of these files
+#! are then scanned for &GAPDoc; documentation comments.
+#!
+#! Default value: [ "gap", "lib", "examples", "examples/doc" ] .
+#!
+#!
+#!
+#!
+## This is the maketest part. Still under construction.
+#! maketest
+#! -
+#! The maketest item can be true or a record. When it is true,
+#! a simple maketest.g is created in the main package directory,
+#! which can be used to test the examples from the manual. As a record,
+#! the entry can have the following entries itself, to specify some options.
+#!
+#! filename
+#! -
+#! Sets the name of the test file.
+#!
+#! commands
+#! -
+#! A list of strings, each one a command, which
+#! will be executed at the beginning of the test file.
