72 | * It'd be nicer if these could be parsed by the build commands, but alas |
73 | * this is not to be. Consider `sw configure --arch=i386-linux |
74 | * --with-diffutils': how is the program to know which options are for it and |
75 | * which are for the remote one? The `configure' command is important, |
76 | * because it does some hairy stuff under the covers (inserting magical |
77 | * options, and running `../configure'), so I can't just require `sw run |
78 | * configure'. Requiring the user to always put in a `--' to separate the |
79 | * two lots of options is horrific. So they get picked up at the main |
80 | * program and stuffed into global variables. |
81 | * |
82 | * On the other hand, there is the advantage that `--output' options can be |
83 | * put in an environment variable here. |
