 Almost all bug fixes or new language additions should come with some additional code samples. Just drop them under [`samples/`](https://github.com/github/linguist/tree/master/samples) in the correct subdirectory and our test suite will automatically test them. In most cases you shouldn't need to add any new assertions.

 ### A note on language extensions
 
 Linguist has a number of methods available to it for identifying the language of a particular file. The initial lookup is based upon the extension of the file, possible file extensions are defined in an array called `extensions`. Take a look at this example for example for `Perl`:

+// Distributions Primer
+//
+// This primer demonstrates uses of some of Chapel's standard
+// distributions.  To use these distributions in a Chapel program,
+// the respective module must be used:
+//
+use BlockDist, CyclicDist, BlockCycDist, ReplicatedDist;
+use DimensionalDist2D, ReplicatedDim, BlockCycDim;
+
+//
+// For each distribution, we'll create a distributed domain and array
+// and then initialize it just to give a brief flavor of how the
+// distribution maps across locales.  Running this example on 6
+// locales does a nice job of illustrating the distribution
+// characteristics.
+//
+// All of these distributions support options to map to a different
+// virtual locale grid than the one used by default (a
+// multidimensional factoring of the built-in Locales array), as well
+// as to control the amount of parallelism used in data parallel
+// loops.  See the Standard Distributions chapter of the language spec
+// for more details.
+//
+
+//
+// Make the program size configurable from the command line.
+//
+config const n = 8;
+
+//
+// Declare a 2-dimensional domain Space that we will later use to
+// initialize the distributed domains.
+//
+const Space = {1..n, 1..n};
+
+//
+// The Block distribution distributes a bounding box from
+// n-dimensional space across the target locale array viewed as an
+// n-dimensional virtual locale grid.  The bounding box is blocked
+// into roughly equal portions across the locales.  Note that domains
+// declared over a Block distribution can also store indices outside
+// of the bounding box; the bounding box is merely used to compute
+// the blocking of space.
+//
+// In this example, we declare a 2-dimensional Block-distributed
+// domain BlockSpace and a Block-distributed array BA declared over
+// the domain.
+//
+const BlockSpace = Space dmapped Block(boundingBox=Space);
+var BA: [BlockSpace] int;
+
+//
+// To illustrate how the index set is distributed across locales,
+// we'll use a forall loop to initialize each array element to the
