168 * The Quake command-line is super basic. It can be entered in the console
169 * or in config files. A semicolon is used to terminate a command and chain
170 * them together. Otherwise, a newline delineates command input.
172 * In most engines, the Quake command-line is a simple linear text buffer that
173 * is parsed when it executes. In Darkplaces, we use a linked list of command
174 * input and parse the input on the spot.
176 * This was done because Darkplaces allows multiple command interpreters on the
177 * same thread. Previously, each interpreter maintained its own buffer and this
178 * caused problems related to execution order, and maintaining a single simple
179 * buffer for all interpreters makes it non-trivial to keep track of which
180 * command should execute on which interpreter.

1359 // alias foo "set x NEW; foo2"
1360 // alias foo2 "echo $x"
1362 // Also note: lines starting with alias are exempt from cvar expansion.
1363 // If you want cvar expansion, write "alias" instead:
1366 // alias foo "echo $x"
1367 // "alias" bar "echo $x"
1370 // foo will print 2, because the variable $x will be expanded when the alias
