Get FTP Server Features (FEAT)

Demonstrates the Chilkat Ftp2.Feat method, which sends FEAT and returns the server's multiline capability reply. It takes no arguments.

Background: FEAT is how a client discovers which optional features a server supports — MLSD for machine-readable listings, UTF8 for Unicode filenames, SIZE, REST for resume, and the AUTH/PROT TLS commands. Chilkat normally runs FEAT automatically and adapts its behavior to the result, so calling it explicitly is mainly for inspection.
