The builtins of an FTE server program: Quake's (QuakeServer.Builtins) and FTE's extensions to them, by number and, for builtins a program binds by name, by name.

QuakeServer.Server.start("c1a0", source: MyGame.Source, builtins: QuakeServer.Extensions)

The families: strings (Strings, Format), recoding (Encoding: strconv, strlennocol, strdecolorize, crc16, uri_escape, uri_unescape, argescape, digest_hex, digest_ptr, base64encode, base64decode, ftou, utof), maths (Maths), entities (Things), entity text (EntityText: generateentitydata, writetofile, parseentitydata, loadfromdata, loadfromfile, find_list, entityprotection), console variables, info keys and reflection (Settings), abort and checkcommand (Control), storage (Store: hash tables, memory, files, searches, string buffers), memory as bytes (Memory: createbuffer, memrealloc, memcmp, memstrsize), files (Files: fwrite, search_getfilemtime, search_fopen, fcopy, frename, fexists, rmtree), string buffers (Buffers: buf_copy, buf_sort, bufstr_find, buf_loadfile, buf_writefile), JSON (Json), the network (Web: uri_get, uri_post, netaddress_resolve, sendpacket), effects, messages, routes, movement, lights, polygons, levels and models.

A builtin neither knows raises QuakeC.Exec.Error.
