libalien-gnuplot-perl - 1.043-1+b1 main

Alien::Gnuplot verifies existence and sanity of the gnuplot external
application. It only declares one access method, Alien::Gnuplot::load_gnuplot,
which does the actual work and is called automatically at load time.
Alien::Gnuplot doesn't have any actual plotting methods - making use of
gnuplot, once it is found and verified, is up to you or your client module.
