64 * It'd be nicer if these could be parsed by the build commands, but alas
65 * this is not to be. Consider `sw configure --arch=i386-linux
66 * --with-diffutils': how is the program to know which options are for it and
67 * which are for the remote one? The `configure' command is important,
68 * because it does some hairy stuff under the covers (inserting magical
69 * options, and running `../configure'), so I can't just require `sw run
70 * configure'. Requiring the user to always put in a `--' to separate the
71 * two lots of options is horrific. So they get picked up at the main
72 * program and stuffed into global variables.
74 * On the other hand, there is the advantage that `--output' options can be
75 * put in an environment variable here.
