+This library provides the GL_EXT_texture_compression_s3tc extenstion for Mesa
+for using precompressed textures with hardware decompression (precompressed
+textures are used by most modern games).
+
+Due to US patent restrictions, this library is not part of Mesa itself.

+# 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.
