+ffproxy is a filtering HTTP/HTTPS proxy server. It is able to filter by 
+host, URL, and header.  Custom header entries can be filtered and 
+added. It can even drop its privileges and optionally chroot() to some 
+directory. Logging to syslog() is supported, as is using another 
+auxiliary proxy server. An HTTP accelerator feature (acting as a 
+front-end to an HTTP server) is included.  Contacting IPv6 servers as 
+well as binding to IPv6 is supported and allows transparent IPv6 over 
+IPv4 browsing (and vice versa).

+# 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.
