[IronPython] Questions about compiled .py files - their stub exe and dlls

[Guy Rozendorn]

Include them where?

Let's look at the following example:
bar.py only has one line: print dir()
I compile using pyc.py to bar.dll and bar.exe
I place bar* and IronPyhton*.dll in C:\Temp\yyy\
If I execute bar.exe from insdie C:\Temp\yyy, it runs without problems.
here's the output:
C:\Temp\yyy\
bar.exe
['__builtins__', '__file__', '__name__']

But, if I try to execute bar.exe from any other directory (for example,
C:\Temp\), it fails:
C:\Temp\
yyy\bar.exe

Unhandled Exception: System.IO.FileNotFoundException: The system cannot find
the file specified. (Exception from HRESULT: 0x80070002)
   at System.Reflection.Assembly.nLoadFile(String path, Evidence evidence)
   at System.Reflection.Assembly.LoadFile(String path)
   at PythonMain.Main()

====

All I want is to be able to execute the compiled python scripts from
whatever directory I want, and not just the directory in which the binary
and all assemblies are in. Is it possilble?
