Currently Net::Google::DocumentsList doesnt publish or export documents.

I posted two gdata-issues reports.

- you can’t export documents other than .pdf file, like .txt or .doc files.

- you can’t grub the published url from the revision feed. The basic functionarities of Net::Google::DocumentsList works. Try testing the module with the commands below

$ perl Makefile.PL
$ make
$ NET_GOOGLE_DOCUMENTSLIST_LIVE_TEST=1 make test
