+Zerofree is a utility which scans the free blocks in an ext2/3/4
+filesystem and fills any non-zero blocks with zeroes.
+
+This is useful if you have an ext2/3/4 virtual disk image
+(e.g. VirtualBox' .vdi) that you wish to compact.
+
+See project homepage for information and usage.

+# 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.
