|  * 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. | ||||
