screenpager
v. 2005.0_alpha

screenpager is a screen-wise desktop pager
for X workstations running Xinerama.
It is similar to an ordinary desktop pager,
but works at the level of screens.
Instead of paging the desktop as a whole,
it can page each screen independently,
or move pages from screen to screen.
