Documentation of @ syntax incomplete

[bengtmartensson]

The documentation for @ syntax is incomplete. It should also say

• many @ files can be used
• the thus expanded @ file is added to the other commands (the present docu suggests replacing)
• they do not nest (i.e. no @'s in @ -included files)
• Empty lines and lines starting with # are ignored.

unless of course some of these features are considered "undocumented".

Does this support overriding of parameters specified in the files via the command line? There's no mention in the documentation of anything of the sort. If not, is it possible that properties files with parameters that are overridable via CLI will be supported or added as a feature any time soon?
