       [ ] Update help index (used by 'whatis' and 'apropos' commands)
       [ ] Update file index (used by 'locate' command)

But all this would a non-issue if we would create these new commands or 
functionality. Then no setup changes would be needed.
* updatewhatis which gets the filelist of the new man files.
* updatedb which should accept a new argument for the package MANIFEST
   to be merged into. Easier just a removal <MANIFEST> and add <MANIFEST>
   option.

On unix it's a non-issue because they have faster forks and esp.
faster filesystems.

$ time makewhatis

real    16m6.209s
user    7m56.942s
sys     2m38.845s

$ time updatedb
/usr/bin/find: /.ssh: Permission denied
/usr/bin/find: Fehler in /etc/mtab: /a.: No such file or directory

real    2m22.452s
user    0m0.674s
sys     0m0.636s

BTW, a nice locate bug eh. algorithmic issue (problematic trigram):

$ locate xx
/bin/cygdb_cxx-3.1.dll
/bin/cygdb_cxx-4.1.dll
/bin/cygdb_cxx-4.2.dll
/bin/cyggmpxx-3.dll
/bin/xxd.exe

$ which /bin/xxd.exe
/bin/xxd.exe: Command not found.

$ ls /bin/??x.exe
/bin/osx.exe  /bin/ptx.exe  /bin/rdx.exe  /bin/tex.exe  /bin/upx.exe

But I'm just too busy right now for this. I have to bring out a new 
release and search for another libtool bug.
Besides the pet cygwin projects.
