-All of Quake's data access is through a hierchal file system, but the contents of the file system can be transparently merged from several sources.
-
-The "base directory" is the path to the directory holding the quake.exe and all game directories. The sys_* files pass this to host_init in quakeparms_t->basedir. This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory. The base directory is
-only used during filesystem initialization.
-
-The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to. This can be overridden with the "-game" command line parameter. The game directory can never be changed while quake is executing. This is a precacution against having a malicious server instruct clients to write files over areas they shouldn't.
-
-The "cache directory" is only used during development to save network bandwidth, especially over ISDN / T1 lines. If there is a cache directory
-specified, when a file is found by the normal search path, it will be mirrored
-into the cache directory, then opened there.
-

-FIXME:
-The file "parms.txt" will be read out of the game directory and appended to the current command line arguments to allow different games to initialize startup parms differently. This could be used to add a "-sspeed 22050" for the high quality sound edition. Because they are added at the end, they will not override an explicit setting on the original command line.

+Word wraps a string. The wordWidth function is guaranteed to be called exactly
+once for each word in the string, so it may be stateful, no idea what that
+would be good for any more. At the beginning of the string, it will be called
+for the char 0 to initialize a clean state, and then once with the string " "
+(a space) so the routine knows how long a space is.
+
+In case no single character fits into the given width, the wordWidth function
+must return the width of exactly one character.
+
+Wrapped lines get the isContinuation flag set and are continuationWidth less wide.
+
+The sum of the return values of the processLine function will be returned.
