The online documentation (e.g. http://ipxe.org/cmd/ifopen), though not yet complete, is far more comprehensive than could be provided within the iPXE binary. Save around 200 bytes (compressed) by removing the command descriptions from the interactive help, and instead referring users directly to the web page describing the relevant command.
