[systemd-devel] Standalone libsystemd

[William Kennington]

I should elaborate that what I would like to see exactly for our use case is
$prefix/include/systemd/*.h
$prefix/lib/lib(systemd|udev).(so*|a)
$prefix/lib/pkgconfig/lib(systemd|udev).pc

Optionally it would be nice to have the man pages for the public APIs
generated.
