+# 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 ':'.

+libtiff: This package provides support for the Tag Image File Format (TIFF),
+libtiff: a widely used format for storing image data. Included is the libtiff
+libtiff: library (for reading and writing TIFF files), and a collection of
