[Bioperl-l] How can I tell if I have certain BioPerl modules? Like Bio::SeqIO

[Warren W. Kretzschmar]

Hi Chet,
This is sort of a hack way to do it, but running a one-liner that
includes the library you'd like to know if you have installed will
throw an error if the library is not installed.

So this should run without error if Bio::SeqIO is installed on your system:
perl -MBio::SeqIO -e 'print "Hello World\n"'

While this will throw an error that the library called Bio::S could
not be found:
perl -MBio::S -e 'print "Hello World\n"'

A nicer way might be to print the module's version number:
perl -MBio::SeqIO -e 'print $Bio::SeqIO::VERSION."\n"'

Because of inheritance, I thin the version number might actually be
the bioperl version number.

Cheers,
Warren
