If it can be useful, this is the code for stripping binaries used for
building unofficial slackware packages:

find . | xargs file | grep "executable" | grep ELF | cut -f 1 -d : |
xargs -r strip --strip-unneeded 2> /dev/null || true
find . | xargs file | grep "shared object" | grep ELF | cut -f 1 -d :
| xargs -r strip --strip-unneeded 2> /dev/null || true
find . | xargs file | grep "current ar archive" | cut -f 1 -d : |
xargs -r strip --strip-unneeded 2> /dev/null || true


If I well remember, this commands must be given at the top level of your
source tree. The above code has been taken from here:

http://repository.slacky.eu/slackware-13.37/scientific/maxima/5.25.1/src/maxima.SlackBuild

I think you can easily save a 50% of disk space by removing debug symbols
(useless for users on an Android device...).

Well, it could be useful for other people to learn :-) I understand your
effort, but keep sure not to violate the GPL by not releasing the source
code of somethind derived from a GPL-ed software (at least for the Maxima
part of your package, the GPL forces you to do release the modified
code...).

I'll look forward for newer versions of your app!

Stefano
