/* glkstart.c: Unix-specific startup code -- sample file.
    Designed by Andrew Plotkin <erkyrath@eblong.com>
    http://www.eblong.com/zarf/glk/index.html

    This is Unix startup code for the simplest possible kind of Glk
    program -- no command-line arguments; no startup files; no nothing.

    Remember, this is a sample file. You should copy it into the Glk
    program you are compiling, and modify it to your needs. This should
    *not* be compiled into the Glk library itself.
