Hi,

I'm interested in building distribution files in multiple spooling
directories for delivery on multiple platforms.  In doing so there was
no way for me to set the location for the interpreter in the final
destination rather than the spooling destination.

Enclosed is a patch that allows me to specify the string to be
substituted in the "#!" line at the beginning of scripts and a
documentation fragment for the new option.

Comments?

thanks

tim

3.4 Listing scripts

So far we have been dealing with pure and non-pure Python modules,
which are usually not run by themselves but imported by scripts.

Scripts are files containing Python source code, indended to be
started from the command line. Distutils provides two features for
scripts.  If the first line of the script starts with #! and contains
the word ``python'' Distutils adjusts the interpreter location.  By
default, it is replaced with the current interpreter location.  The
'--executable=/-e' switch will allow the interpreter path to be
explicitly overridden.

The scripts option simply is a list of files to be handled in this
way.
