Hello, 
 
 Thanks for the tips, I have already started playing around and thought a
 good place to start would be to copy sybase as an orm sheet with three
 figures (just renamed existing sybase figure files).
 
 I have added orm code in :
 
 objects/orm
 objects/Makefile.am
 
 po/POTFILES.*
 
 shapes/orm
 shapes/Makefile.am
 
 sheets/orm.sheet.in
 sheets/Makefile.am
 
 I run ./autogen.sh, ./configure and make.
 
 I seem to see the actual plugins being built in objects (no sybase or
 orm), all builds ok, no errors and only see sybase as a tab with the
 icons. I was hoping to see orm tab... I must be missing something, but
 not sure what. Ideas?
 
Thanks,
erics
