I runs

{{{
R2spec -u http://www.bioconductor.org/packages/release/bioc/src/contrib/Rintact_1.2.0.tar.gz --bioc
}}}

The resulting spec file has a description field set to the text that appears here (black text in a blue box underneath the package title and summary):

http://www.bioconductor.org/packages/release/bioc/html/Rintact.html

Ah... I see this comes from the "Description:" field in the 'DESCRIPTION' file in the package...

My point was, how come the "Summary:" field of the spec file isn't set to the text that appears on the above URL, namely "Interface to EBI Intact protein interaction data base".

Actually this text seems similar to the "Title:" field in the 'DESCRIPTION' file in the package...

"Interface to EBI Intact protein interaction data base"

So, can the spec file take its "Summary:" field from the DESCRIPTION file's "Title:" field?
