// cmd.h -- Command buffer and command execution
//===========================================================================
/*
Any number of commands can be added in a frame, from several different sources.
Most commands come from either keybindings or console line input, but remote
servers can also send across commands and entire text files can be execed.
The + command line options are also added to the command buffer.
The game starts with a Cbuf_AddText ("exec quake.rc\n"); Cbuf_Execute ();

// the text is added to the end of the command buffer.

// inserted at the beginning of the buffer, before any remaining unexecuted
// commands.
