[CVS commit program]

Update of /anoncvs/pvfs2/doc
In directory parlweb1:/tmp/cvs-serv12929/doc

Modified Files:
	pvfs2-quickstart.tex 
Log Message:
Gossip'ized kmod as well so that we dont have 2 separate calls to printing diagnostics.
gossip for the kmod is fairly primitive and is handled simply by means of a macro in gossip.h.
Replaced and removed pvfs2_print and pvfs2_error with gossip_debug.
Edited quickstart to include comments on the new kmod debug parameters as well.
