[Templates] csv file to template data file

[Rick]

Currently I'm creating the $csv_data by running the above perl script from
the command line. Then I'm using ttree to process the templates. I know this
is awkward, which is why I posted here.

I think that I should call the perl script from within TT2, creating
$csv_data which can then be used by other templates. Is that right? If so,
what is the best way to call a perl script from TT2? Also, if I then run
that script and generate $csv_data from within a preprocessed template, is
that data accessible to other templates?

Hoping I'm making sense...
