Modifying the PATH envariable

[Robert James]

Our app invokes some binary executables (imagine `convert image.png`).
In order to make deployment error free, I'd like to include them in our
source tree, and add the paths to the ENV['PATH'] dynamically.

Is there a cross platform way of doing this? Unix uses ':' as a path
separator, Windows uses ';'.

In case you're wondering how the binaries can be cross platform.
Imaging:
/vendor/bin/i386-linux/
/vendor/bin/i386-mswin32/
require 'rbconfig'
add_to_path('vendor/bin/' + Config::CONFIG['arch'] + '/')

Not sure how to compile cross Linux binaries, though - they're often
dependent on the distro and even version. Is it enough to compile them
statically linked?

Can anyobdy get me started with this?

If it's in the source tree, maybe you can use full paths in the invocation.

File:ATH_SEPARATOR, http://www.rubycentral.com/book/ref_c_file.html
ENV['PATH'] << File:ATH_SEPARATOR << 'new.dir'
