# 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 ':'.

clamav:
clamav: Clam AntiVirus is a GPL anti-virus toolkit for UNIX. The main purpose
clamav: of this software is the integration with mail servers (attachment
clamav: scanning). The package provides a flexible and scalable multi-threaded

clamav: Internet. The programs are based on a shared library distributed with
clamav: the Clam AntiVirus package, which you can use with your own software.
clamav: Most importantly, the virus database is kept up to date.
