+gruntmaster-compile - Gruntmaster 6000 compiler frontend
+
+=head1 SYNOPSIS
+
+  gruntmaster-compile CPP file.cpp
+  gruntmaster-compile JAVA file.java
+
+=head1 DESCRIPTION
+
+gruntmaster-compile is a very simple frontend to various comilers. It takes two arguments: the file format and the file name, and produces a compiled executable. The executable's name is the basename of the input file.
+
+Compile commands for each format:
