Relative path for all javascript inputs and outputs

[GoogleCodeExporter]

I understand that start path for config options related to javascript files 
(and catalogs) is always a location of a config json file, right? And there is 
no way to change it.

Can you add option ("root-path" for example) that would be a start location for 
relative paths in options:
- inputs (separated and inside "modules")
- paths
- externs (local)
- closure-library
- output-file
- module-output-path
- module-info-path
- jsdoc-html-output-path
- variable-map-input-file, variable-map-output-file, property-map-input-file, 
property-map-output-file
- test-template
?

Start path for this "root-path" could be location of a config file, and it 
could defaults to ".".
