Bug#368383: dumb "manual page for..." NAME section on many man pages

["A. Costa" <agcosta@gis.net>]

This mostly works for '.deb' files.

	# print the archive name and the 'whatis' line of any man pages in it.
	dope() { D=$1 ; dpkg-deb -c $D | grep '^-.*man' | while read a b c d e f ; do echo $f ; done | while read x ; do basename $x ; done | tr . ' ' | while read a b c ; do L="`bash debman -f $D $b $a 2> /dev/null | grep -m 1 -A 1 "NAME" | tail -n 1`"; [ "$L" ] && echo "$D , $a.$b:$L" ; done ; }

Example:
	% dope bash_3.1-4_i386.deb 
	bash_3.1-4_i386.deb , bash.1:       bash - GNU Bourne-Again SHell 
	bash_3.1-4_i386.deb , bashbug.1:        bashbug - report a bug in bash 
	bash_3.1-4_i386.deb , clear_console.1:       clear_console - clear the cons ole
	bash_3.1-4_i386.deb , rbash.1:       rbash - restricted bash, see bash(1)
	bash_3.1-4_i386.deb , bash-builtins.7:       bash-builtins - bash built-in commands, see bash(1)

Doesn't check for hard or soft links, yet.

Change to a dir with lots of '.deb' files, and this runs slow:

	 for f in *.deb ; do dope $f ; done | grep "manual page for"

HTH...
