# Strip binaries and libraries - this can be done with 'make install-strip'

#find $PKG -print0 | xargs -0 file | grep -e "executable" -e "shared object" | grep ELF \
#  | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null || true

# Compress man pages
# If the man pages are installed to /usr/share/man instead, you'll need to either
# add the --mandir=/usr/man flag to configure or move them manually after the
# make install process is run.
