X11::XCB::Atom - wraps an X11 atom
Returns whether this atom actually exists. If the id of the atom has not been requested before, this generates a round-trip to the x server. This is very likely, as id() dies if the atom does not exist.
To install X11::XCB, copy and paste the appropriate command in to your terminal.
cpanm
cpanm X11::XCB
CPAN shell
perl -MCPAN -e shell install X11::XCB
