How do I add my own __MVC_MYOWN___ Macro

["Kyle D. Chen" <kyle.chen@stanford.edu>]

Hi! Mike,

I'm trying to add new variables to the simple template in the catalog.cfg file, and I'd
like to add new variable macros that makecat would substitute for me.  The document says
that I can run a "pre-qualifying" script to set the environment variable __MVC_MYOWN__ and
then add it in the catalog.cfg as well as in the additional_fields file so that makecat
would recognize it....

But, how do I do this "pre-qualifying" script?

Please help.  Many thanks.

Kyle
