To compile (to .mjs), use compile or c.
To compile (to .js), use legacy-compile or lc.
Those two are exactly the same except for the file extension.
--map will add the line numbers of the source to the generated code. Useful for debugging. (Note: this is not "source map", which is another technology.)
Because we use a very sophisticated versioning model that all historical compilers are kept, there's really no need to install it to your project directory - conflicts are very unlikely. But if you really "hate global", to avoid waste of disk space, it should be stated in "devDependencies", not "dependencies" (particularly when you're writing a middleware).
Compile "a.fus" to "a.mjs":
fus compile a.fusCompile for debugging:
fus compile --map a.fusCompile the whole "lib" directory to "target":
fus compile lib targetSee "develop.md".
