+zpaq is a journaling, incremental, deduplicating archiver for Windows
+and Linux.
+
+"Journaling" means that when you update a file or directory, both the
+old and new versions are saved. You can extract from the archive as it
+existed at any time in the past. "Incremental", means that when you back
+up your entire hard drive, for example with:
+
+  zpaq -add e:backup.zpaq c:\*
+
+only those files whose last-modified date has changed since the previous
+backup are added. For 100 GB of files, this typically takes 1-2 minutes,
+vs. a few hours to create the first version. "Deduplicating" means that
+identical files or fragments are stored only once to save time and space.

+# 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.
