it's a Linux/UNIX command, short for "manual"; and wget is a non-interactive file retrieval utility for Linux/UNIX; so the `man wget' command, executed in your shell, will display on your terminal wget's manual pages
on a side note, it never ceases to amaze me how people without a slightest clue about Linux/UNIX commands and using these operating systems in general, manage to compile, run and support software like eggdrop... (no offense to you jailmann)
well, just *another* stupid idea:
why don't you use http.tcl and ftp.tcl ?
they are useful packages for eggdrops and the way to use them is really simple.
And more: you're never sure that wget (or lynx or any text-based browser) is on your shell.
