+LPeg is a new pattern-matching library for Lua, based on Parsing Expression
+Grammars (PEGs).
+
+The library offers several functions to create and compose patterns. With the
+use of metamethods, several of these functions are provided as infix or prefix
+operators. On the one hand, the result is usually much more verbose than the
+typical encoding of patterns using the so called regular expressions (which
+typically are not regular expressions in the formal sense). On the other hand,
+first-class patterns allow much better documentation (as it is easy to comment
+the code, to break complex definitions in smaller parts, etc.) and are
+extensible, as we can define new functions to create and compose patterns.

+# 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.
