[flext] Building individual externs from command line

[Jamie Bullock]

Hi,

It's quite straightforward to set Xcode up so that externals can be built as a library or individual externs.

I see xsample uses this pattern, for example.

Is there a neat way to do this using the command-line build system?

I guess a clunky way would be to have multiple "package" files and then copy each one to "package.txt" before calling "build.sh" in a kind of master build script.

Better way?
