Currently both sodepends and soprovides have to be specified in the
PKGBUILD:
sodepends=(libreadline.so libc.so)
soprovides=(libreadline.so)
Versions and arch will be added afterwards and the final line in
.PKGINFO looks like this:
provides = libreadline.so-elf64_x86_64=6
For the arch part a better way to find the arch of the lib would be
nice. Neither readelf nor objdump seem to fit. Readelf only shows 32/64
and objdump shows i686 libs as i368. If anyone has an idea please share.
