+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+ragel: ragel (State Machine Compiler)
+ragel:
+ragel: Ragel compiles executable finite state machines from regular
+ragel: languages. Ragel targets C, C++, Objective-C, D, Java and Ruby.
+ragel: Ragel state machines can not only recognize byte sequences as regular
+ragel: expression machines do, but can also execute code at arbitrary points
+ragel: in the recognition of a regular language. Code embedding is done using
+ragel: inline operators that do not disrupt the regular language syntax.
