+# Changes the prompt to a Debian-style one that truncates pwd to a max length
+# depending on the terminal column width. Also uses the prompt_callback 
+# function of bash-git-prompt to set the window title to almost the same 
+# Debian-style.
+#
+# The prompt will use a Debian-style on the form
+#
+# [user@host: <truncated PWD>] [bash-git-prompt-info] <exit status>
+# HH:MM $ 
+#
+# The window title will have the form
+# user@host: <truncated PWD>
+#
+# Example usage:
+# if [ -f ~/.bash-git-prompt/gitprompt.sh ]; then
+#   GIT_PROMPT_THEME=Default_TruncatedPwd_WindowTitle
+#   source ~/.bash-git-prompt/gitprompt.sh
+# fi
