Suppose that I have a project which (should be)/is multiplatform in

which, however, uses some executables as black-boxes.
These executables are platform-dependent and at the moment they're just
thrown inside the same egg, and using pkg_resources to get the path.
I would like to rewrite this thing being able to:
- detect the OS
- find the right executable version
- get the path and run it
It would be nice to still be able to use pkg_resources, but at that
point I think
I would need to store all the executables in another egg, is that
correct?
Is there already something available to manage external multi-platform
executables?
Thanks,

The most simple possible way I can think of to solve this problem would
be, to create
a directory for each executable, and in each directory the executable
with the platform
in the name, like:
- exec1:
+ exec1-linux2
+ exec1-darwin
...
And to look up would be very simple (as below), but I feel that is not
very smart...
import sys
from os import path
BASE_DIR = '.'
exec_name = sys.argv[1]
assert path.isdir(exec_name)
plat = sys.platform
name_ex = "%s-%s" % (exec_name, plat)
if plat == 'win32':
name_ex += '.exe'
res_ex = path.join(exec_name, name_ex)
assert path.isfile(res_ex)
print path.abspath(res_ex)
