That should be doable, but I don't think it's a good idea. For
starters, I don't see it getting used too much; the slack-desc file is
just unlikely to have exactly what you're looking for.  False-positives
and false-negatives would (I imagine) be pretty high.  The code to do
it isn't too complex though.


# WARNING: The following code is completely untested and subject to
#result in death or dismemberment
echo -n "Enter search terms in regular
expression: "
readline GREP_REGEX
find . -type f -name "slack-desc" | (while read SD; do
  APP=$(dirname "$SD" | cut -d '/' -f 2)
  if grep "$GREP_REGEX" "$SD" >/dev/null 2>&1; then
    # APP contains the regex
    echo "$APP matches"
  fi
done)

Of course, you'd want to eliminate the comments that often are at the
top of the slack-desc file, and it would be nice to concatenate all the
valid lines of the slack-desc file together without the annoying
PRGNAME: prepend to each of them.  Oh yeah, you'd want to filter out
the handy ruler for perfection.  In short, the slack-desc file just
doesn't lend itself well to these kind of searches, not least of all
because it might not include the same kind of information the package
tags contain.
