+At least on my system (ubuntu) many programs feature auto-completion of subcommands; it is very useful. Fossil does not, svn and cvs do.
+
+My guess is that the feature is enabled by the following entry in .bashrc:
+
+<verbatim>
+# enable programmable completion features (you don't need to enable
+# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
+# sources /etc/bash.bashrc).
+if [ -f /etc/bash_completion ]; then
+    . /etc/bash_completion
+fi
+</verbatim>
+
+It would be nice if we could develop and maintain a file that would enable this for fossil when copied to /etc/bash_completion.d. I do not know if this can be made in a portable (or at least automated) manner at all.
