#    zipgrep: Use unzip and egrep to search the specified members of a
# Zip archive for a string or pattern.  Search all members if no members
# are specified explicitly.  The script attempts to handle egrep's &quot;-h&quot;
# and &quot;-l&quot; options internally.
#
# This script assumes that the desired &quot;unzip&quot; and &quot;egrep&quot; (and &quot;sed&quot;)
# programs are on the user's PATH.
