+icdiff (improved color diff)
+
+Show differences between files in a colorful two column view. Can be
+used with as a "git diff" replacement, via "git-icdiff" command.
+
+Note: It's highly recommended to use wide terminals with icdiff, for
+instance 160 columns or more.
+
+icdiff is similar in concept to colordiff, but it uses a two column
+"side by side" format.

+# 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.
