True, X is a "network-based windowing system" that provides tools for an
interface.

Actually, just this past Fall I wrote a program that displayed formatted
source code.  When the user selected a variable name by clicking on it, the
program sent some information <down a pipe> to the next tool.  Powerful stuff.

That's definitely true. (about the library)  And when you consider the
size of the ROM and what it could possibly be used for, like it can be
used by *any* application (and is), it's quite efficient, now that I
actually think about it....

That's all they are used for??
