A very handy script I use to manage several projects, like haiku, oss, ...

It adds a "dev" function which completes on project names, sources local .profile and uses local .bash_history, as well as other niceties.
See comments on how to use it.

+# project-specific environment handling:
+# - sources project-specific .profile,
+# - maintains project-specific .bash_history with bigger default size,
+# to avoid mixing command histories
+# - pushes "cvs up -d" or "svn up" or "p4 sync" as last history command
+# for quick access
+# - has a nice prompt
+# - lowers shell priority on BeOS to limit the effects of svn or jam on
+# the gui
+# - automatically completes project names on the "dev" function
+# from project subfolders containing a .profile
+#
+# This script should be sourced by bash, either from /etc/profile
+# (in /etc/profile.d/) or your own .bashrc or .profile
+# 
+# setup:
+# - edit DRLIST below to include your own possible devroots
+# (ie. where you have subfolders for your own projects)
+# - optionally edit PWLIST below to where you possibly have a
+# PASSWDS/ folder with passwords stored as plain text.
+# (not really a good idea though :) It's exported
+# for use by project's .profile
+# - optionally force EDITOR globally (for all projects)
+# - for each project create a .profile in the subfolder,
+# which might include commands like the following, but can remain empty.
+# usually it will just contain a "cd" to the source/trunk subfolder...
+#
+#	# force svn ssh user for this project
+#	export SVN_SSH='ssh -l myuser'
+#
+#	# force CVSROOT for this project
+#	export CVSROOT='...'
+#
+#	# shortcut to display password file for this svn
+#	alias pass="cat $PASSWDS/myself.developer.berlios.de.pass"
+#
+#	# change to the source tree
+#	cd trunk
+#	# ease use of cd
+#	export CDPATH=":$PWD"
+#
+# Now you just have to type:
+# dev h[TAB]
+# to complete to "dev haiku", [RET] and you'll get the history from the
+# last time you worked on it, and everything set up.
+
+
+# automagically find them on different machines...
