+backports.lzma - Provides support for LXMA and XZ compressed files via the
+XZ Utils C library.
+
+This code is a backport of the Python 3.3 standard library module lzma for
+use on older versions of Python where it was not included.
+
+There are some older Python libraries like PylibLZMA and PyLZMA but these
+use LZMA Utils (not XZ Utils, so they have no XZ support).

+# 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.
