# ptxdeb public domain 12/14/98 by John Hasler 

# ptxdeb uses the GNU permuted index program ptx to produce KWIC indexes of
# the Debian Packages file.  Requires a fixed ptx.  ptx_0.4-5 is broken.

CONFFILE="/etc/ptxdeb/ptxdeb.conf"
PACKAGES=`cat $CONFFILE`

usage () { echo "$VERSION usage: ptxdeb keyword
Edit /etc/ptxdeb/ptxdeb.conf to read a different Packages file."; }

case "$#"
in
    0)  cat $PACKAGES | awk '/Package:/ { printf "%s", $2 }; \
                   /Description:/ { $1 = ""; print}' | ptx -r ;;

Hack it to operate on Available instead of Packages and add bells and
whistles to taste.
