pyxtrlock -- The leightweight screen locker rewritten in Python
---------------------------------------------------------------

pyxtrlock is a very limited transparent X screen locker inspired by Ian
Jackson’s great xtrlock program. pyxtrlock uses modern libraries, most
importantly the obsolete direct passwd/shadow authentication has been replaced
by today’s PAM authentication mechanism, hence it also works on Fedora. Also,
it’s mostly written using XCB instead of Xlib.
