toolkit/components/commandlines/public/nsICommandLineHandler.idlScriptable Handles arguments on the command line of a XUL application. 1.0 66 Introduced Gecko 1.8 Inherits from: nsISupports Last changed in Gecko 1.8 (Firefox 1.5 / Thunderbird 1.5 / SeaMonkey 1.0)

Each command line handler is registered in the category "command-line-handler". The entries in this category are read in alphabetical order, and each category value is treated as a service contract ID implementing this interface.

By convention, handlers with ordinary priority should begin with "m".

Example:

command-line-handler	b-jsdebug	@mozilla.org/venkman/clh;1
command-line-handler	c-extensions	@mozilla.org/extension-manager/clh;1
command-line-handler	m-edit	@mozilla.org/composer/clh;1
command-line-handler	m-irc	@mozilla.org/chatzilla/clh;1

By convention, the right column which contains flag descriptions begins at the 24th character. Read only.
