* ftplib.c : Low-level routines for opening and using ftp connections.\
*\
* George Ferguson, ferguson@cs.rochester.edu, 29 Nov 1992.\
*\
* Based on ftplib by Amos Shapira (amoss@cs.huji.ac.il) and code\
* from Alan Emtage (bajan@bunyip.com) and RFC 959.\
*\
This is an Object category that provides methods for most of the functions\
defined in ftplib.c. The methods are based on, or are direct translations of the\
routines in ftplib.c.\
