-/*
- * minigzip is a minimal implementation of the gzip utility. This is
- * only an example of using zlib and isn't meant to replace the
- * full-featured gzip. No attempt is made to deal with file systems
- * limiting names to 14 or 8+3 characters, etc... Error checking is
- * very limited. So use minigzip only for testing; use gzip for the
- * real thing. On MSDOS, use only on file names without extension
- * or in pipe mode.
