The new development version of PCA (20110928-01) supports multiple URLs and path 
names with the "patchurl" and the "xrefurl" option. Example:

   pca --patchurl "file:/patches http://www/pca/pca-proxy.cgi"

Or in a configuration file:

   patchurl=/patches http://www/pca/ oracle

The special keyword "oracle" can be used to specify Oracle's patch server. 
Formerly, PCA always tried to access the Oracle server if a patch wasn't to be 
found on "patchurl". Now this must be explicitely specified, giving you total 
control over the locations tried by PCA to access patches, patch READMEs and the 
patchdiag.xref file. Hopefully this change in behaviour won't be confusing - the 
gain in control is worth it, I guess.

Quite a lot of code was touched for this change, so I'd be happy about everybody 
testing this new development version.
