I was just wondering if its possible to inherit mapping files for code generation purposes ?

Fo eg.. I have abt 50 mapping files that I generated by reverse engineering.
Since I want all my generated classes to extend a partuclar class and implement an interface, I have to modify the mapping file to add a meta tag that specifies this info... This has to be done for all 50 files... Just wondering, if there is a way to specify this in a new mapping file and have the rest of the 50 mapping file inherit the meta definitions present in this new file...

it is not optimal, but reveng.xml supports adding in <meta> attributes into reverse engineered classes. we have an outstanding issue to fix to allow you to specify it more generically.
