To create the C implementation bindings for a set of SIDL classes,
Babel should be invoked as follows
% babel -exclude-external -server=C file.sidlor use the short form
% babel -E -sC file.sidl
The command creates a number of files. Specifically, a makefile fragment, called babel.make, headers, and source files are generated. The only files needing hand-editing are the C ``Impl'' files -- which are header and source files whose names end in _Impl.h or _Impl.c, respectively. More on this in Subsection 6.4.2.
