[Proj] Command Line Utility(ies) to Transform Shape Files

[Kevin M.]

Hello,

Does anyone out there know if there are any command line utilities with Windows 
version that could be used to perform a NAD27 to WGS84 conversion on an 
existing shape file?  I would prefer these to be true command line utilities 
rather than perl or python scripts if possible.

I have used nad2nad for similar purposes on text files, but I don't know of a 
simple way to run nad2nad on a shape file.

Thanks,
Kevin M.
