It basically provides two functions: code alignment and snippet
insertion.  To align code, use `gnome-c-style-align-decls-region'
to line-up multiple function declarations in region, and
`gnome-c-style-align-arglist-at-point' to line-up arguments in the
argument list at point.

To insert code snippet, use `gnome-c-snippet-insert'.  The command
will let you choose a template to be inserted.  This package also
provide commands to insert package/class names in upper case,
capital case, and lower case.  For complete list of commands, do
M-x describe-bindings.
