lafe — Latency Free Empire client
Synopsislafe country [password [host [port]]]
Descriptionlafe is an empire client optimized for high latency links. You can type in, edit, and send several commands before the server replies with output from the first command. This allows you to make better use of the existing bandwidth than most other clients. pei and eif are particularly susceptible to latency, as they require a complete exchange of data before prompting again. lafe could also be called LAg Free Empire. Empire 2 asynch features are supported. Empire 3 C_SYNC isn't supported, as this is a rather dumb client (in between emp_client and eif) and C_SYNC was removed from Empire 4 (Wolfpack). Readline is supported, and at the moment required. If you want lafe without readline, use emp_client instead.

BugsOutput redirection does not work with aliases and internal commands. Simultaneous connection to multiple servers is not yet supported. Version 1.0 addresses both of these issues, but has stalled due to lack of time.
When typing well ahead of the server, lafe must guess whether a local command should be parsed locally or forwarded to the server (as part of a telegram for instance). It guesses local, which is not always correct. This is the price you pay for speed.
