vc-clearcase.el is a ClearCase integration package that works as a client to the Emacs VC package. In addition to the standard VC functionality, this package supports ClearCase specific tasks such as updating static views, edit a view's configspec, list checkouts and start the version tree browser GUI on a file. UCM is also supported. NOTE: this version will not work with Emacs releases prior to version 23. To install the package, follow these steps: 1/ Copy this directory under the site-lisp directory of your GNU/Emacs installation 2/ Byte compile vc-clearcase.el and ucm.el. You can do it from inside Emacs, or from the command line: % emacs -batch -f batch-byte-compile vc-clearcase.el % emacs -batch -f batch-byte-compile ucm.el 3/ Add the following line to your initialization file (~/.emacs.el): (load "vc-clearcase-auto") The ClearCase backend should activate when you open a file inside a ClearCase view.
