Module JAR needed for generating the info file.
Information may be gotten either from its manifest,
or if it declares OpenIDE-Module-Localizing-Bundle in its
manifest, from that bundle.
The base locale variant, if any, is also checked if necessary
for the named bundle.
Currently no other locale variants of the module are examined;
the information is available but there is no published specification
of what the resulting variant NBMs (or variant information within
the NBM) should look like.
