# 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 ':'.

librsync:
librsync: librsync implements the rolling-checksum algorithm of remote file
librsync: synchronization that was popularized by the rsync utility and is used
librsync: in rproxy. This algorithm transfers the differences between 2 files
librsync: without needing both files on the same system.
