Xtla is the Emacs front-end to the GNU Arch revision control
system. It provides user-friendly wrappers for tla native
commands and some higher level features such as the
bookmark manager. The main features are a PCL-CVS-like
interface for tla inventory and tla changes, an archive browser,
good integration in Emacs, a bookmark manager, integration
with ediff, Emacs's graphical diff tool, an interface to view
missing patches from all your partners with a single command,
and an Emacs mode for arch-related files (log files, =tagging-
method).
