In case you were interested in developing HelenOS-specific
applications out-of-tree, it shouldn't be much trouble to support that
kind of workflow.

However, in practice, HelenOS-specific application only makes sense if
you are using HelenOS-specific features and APIs, and those APIs are
not stabilized, so there would be no guarantee for that application to
keep working with new HelenOS release.

On the other hand, if you want to write an application that doesn't
strictly require HelenOS-specific features to work, it would be
preferrable to write an application designed portably, with an
abstraction layer for things that differ between systems. This is my
personal opinion, but I consider unnecessarily platform-locked
applications to be a nonsensical burden. An application that can run
on other systems in addition to HelenOS would be much easier to
maintain and debug than one designed specifically for HelenOS only.

I'll be improving this are in coming months. If you have issues, or
there are missing POSIX library functions you need, I'm currently the
best person to ask for help. Feel free to send me a message, and you
can also find me on our IRC channel, under the name "jzr". :)

GitHub is the gold standard right about now.
You can publish whatever you are working on in your own personal
repos, and inform the community about it via this mailing list.
