format_skeleton.cc

/*

    Format converter module skeleton.

    Steps to create a new format.

    1) Copy this file to <your_format_name>.c
    2) Rename all format_skeleton tokens to <your_format_name>.
    3) Replace the fictional name and address in the Copyright section below.
       ** As your work is likely built on the work of others, please retain
       the original line. **
    4) Create a new section in vecs.c.
    5) Add compilation instructions to Makefile.
    6) Add sample files (it's better when they're created by the "real"
       application and not our own output) to reference/ along with
       files in a well supported (preferably non-binary) format and
       entries in our 'testo' program.   This allows users of different
       OSes and hardware to exercise your module.
