GlkLoader is an implementation of the the Glk specification which simply loads another Glk library and passes all Glk calls through to it. The purpose is to allow a single executable to choose which Glk library to use at run-time, instead of at compile-time.

with the various Unix Glk libraries -- at least, the three I wrote.
|
|
(I encourage anyone writing a Unix Glk library to use this interface,
|
|
but it's not part of the Glk spec.)
|
|
|
|
Because Glk is *almost* perfectly portable, this interface *almost*
|
|
doesn't have to exist. In practice, it's small.
