wrap: support for existing directories

[nioncode]

It would be nice to have a syntax for a wrap.file that allows to use an already downloaded folder (or mapped network drive or whatever) as subproject source.

somelib.wrap:

[wrap-directory]
directory = somelib
source_directory = /mnt/network/somelib

someother.wrap:

[wrap-directory]
directory = someother
source_directory = ../libs/someother

You don't need wrap for that. If you have a subdir (or symlink) with the name foo in your subproject folder, it is used automatically. How you populate it is up to you.

Sure, I can set this up manually with a symlink.
I can also checkout a git repository or download a tarball and extract it, both of which are supported by wrap.

Also, symlinks are not cross platform portable, e.g. they don't work on Windows when checked out from git. A wrap file would take care of this issue, since it copies the source directory.
