[flexcoders] asdoc not supporting path variable in config file.

[sehrawat_raj]

In Flexbuilder 3, sdk 3.2.0,
I have setup a flex project in which Additinal compiler arguments 
"-load-config" is used to define my own config file.

In this config file I am using a path variable "OVCodebaseDir" created from 
FlexBuilder preferences -> General -> Workspace -> Linked Resources.

The project gets compiled without error and runs well.

But using the launch files, I am generating documentation for the project, 
which gives error
"...Codebase\App\OV-config.xml(34): Error: configuration variable 
'compiler.theme' value contains unknown token 'OVCodebaseDir'
        </theme>
"

the settings in launch file is 
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_TOOL_ARGUMENTS" value="
 -source-path ./src 
 -doc-sources ./src 
 -output=../../Docs/OVAppDocs 
 -load-config+=OV-config.xml 
 -library-path &quot;${FlexRoot}/frameworks/libs&quot; 
 -library-path 
&quot;${FlexRoot}/frameworks/libs/player/{targetPlayerMajorVersion}&quot; 
 />


The "FlexRoot" variable was defined in FlexBuilder preferences -> Run/Debug -> 
String Substitution.
I even tried creating "OVCodebaseDir" variable here.

If I replace OVCodebaseDir with absolute path in config file then I am able to 
generate the documentations. So there is no problem in launch file.

How to declare/define custom variables used for config file?

Thanks,
