This is both a library and a set of simple scripts for reading information about a Google PicasaWeb account.
If you download it from github, you will need to install it using Dist::Zilla.
cpanm Dist::Zilla
dzil authodeps | cpanm
dzil install
Probably, however, you will want to install it from CPAN.
cpanm Net::Google::PicasaWeb
or, if you don't have cpanm available:
perl -MCPAN -e 'install Net::Google::PicasaWeb'
