NAME

       backend-spec - interface between jw and its backends

DESCRIPTION

       jw(1) calls backends like backends/html to do the "real" conversion work. The backend gets
       all necessary data delivered via environment variables ready to use.

       This documentation describes those environment variables.

       The backend is run in the directory where the output files are to be  created.  It  should
       return 0 if there weren't any problem, and return a positive value otherwise.
