Some of the "create-component" self documentation is not clear.
Also the abiltiy to specify

[moduleName:]

should be removed as it makes referencing pages more complicated. (The addAvailability command should be updated in this way.)

Fix to:
Creates a component and optionally makes it available (or autogenerated) in a given area of a page. E.g. mgnl create-component foo -a myPage@main -p /path/to/module

-a, --available <[relPath/]page@area> Make available on page in area
-g, --autogenerate <[relPath/]page@area> Autogenerate on page in area
