+IBM VisualAge C/C++ for OS/2
+============================
+
+To build Python for OS/2, change into ./os2vacpp and issue an 'NMAKE'
+command. This will build a PYTHON15.DLL containing the set of Python
+modules listed in config.c and a small PYTHON.EXE to start the
+interpreter.
+
+By changing the C compiler flag /Gd- in the makefile to /Gd+, you can
+reduce the size of these by causing Python to dynamically link to the
+C runtime DLLs instead of including their bulk in your binaries.
+However, this means that any system on which you run Python must have
+the VAC++ compiler installed in order to have those DLLs available.
+
+During the build process you may see a couple of harmless warnings:
+
+ From the C Compiler, "No function prototype given for XXX", which
+ comes from the use of K&R parameters within Python for portability.
+
+ From the ILIB librarian, "Module Not Found (XXX)", which comes
+ from its attempt to perform the (-+) operation, which removes and
+ then adds a .OBJ to the library. The first time a build is done,
+ it obviously cannot remove what is not yet built.
+
+This build includes support for most Python functionality as well as
+TCP/IP sockets. It omits the Posix ability to 'fork' a process but
+supports threads using OS/2 native capabilities. I have tried to
+support everything possible but here are a few usage notes.
+
+
+-- os.popen() Usage Warnings
+
+With respect to my implementation of popen() under OS/2:
+
+ import os
+
+ fd = os.popen("pkzip.exe -@ junk.zip", 'wb')
+ fd.write("file1.txt\n")
+ fd.write("file2.txt\n")
+ fd.write("file3.txt\n")
+ fd.write("\x1a") # Should Not Be Necessary But Is
+ fd.close()
+
+There is a bug, either in the VAC++ compiler or OS/2 itself, where the
+simple closure of the write-side of a pipe -to- a process does not
+send an EOF to that process. I find I must explicitly write a
+control-Z (EOF) before closing the pipe. This is not a problem when
+using popen() in read mode.
+
+One other slight difference with my popen() is that I return None
+from the close(), instead of the Unix convention of the return code
+of the spawned program. I could find no easy way to do this under
+OS/2.
+
+
+-- BEGINLIBPATH/ENDLIBPATH
+
+With respect to environment variables, this OS/2 port supports the
+special-to-OS/2 magic names of 'BEGINLIBPATH' and 'ENDLIBPATH' to
+control where to load conventional DLLs from. Those names are
+intercepted and converted to calls on the OS/2 kernel APIs and
+are inherited by child processes, whether Python-based or not.
+
+A few new attributes have been added to the os module:
+
+ os.meminstalled # Count of Bytes of RAM Installed on Machine
+ os.memkernel # Count of Bytes of RAM Reserved (Non-Swappable)
+ os.memvirtual # Count of Bytes of Virtual RAM Possible
+ os.timeslice # Duration of Scheduler Timeslice, in Milliseconds
+ os.maxpathlen # Maximum Length of a Path Specification, in chars
+ os.maxnamelen # Maximum Length of a Single Dir/File Name, in chars
+ os.version # Version of OS/2 Being Run e.g. "4.00"
+ os.revision # Revision of OS/2 Being Run (usually zero)
+ os.bootdrive # Drive that System Booted From e.g. "C:"
+ # (useful to find the CONFIG.SYS used to boot with)
+
+
+-- Using Python as the Default OS/2 Batch Language
+
+Note that OS/2 supports the Unix technique of putting the special
+comment line at the time of scripts e.g. "#!/usr/bin/python" in
+a different syntactic form. To do this, put your script into a file
+with a .CMD extension and added 'extproc' to the top as follows:
+
+ extproc C:\Python\Python.exe -x
+ import os
+ print "Hello from Python"
+
+The '-x' option tells Python to skip the first line of the file
+while processing the rest as normal Python source.
+
+
+-- Suggested Environment Variable Setup
+
+With respect to the environment variables for Python, I use the
+following setup:
+
+ Set PYTHONHOME=E:\Tau\Projects\Python;D:\DLLs
+ Set PYTHONPATH=.;E:\Tau\Projects\Python\Lib; \
+ E:\Tau\Projects\Python\Lib\plat-win
+
+The EXEC_PREFIX (optional second pathspec on PYTHONHOME) is where
+you put any Python extension DLLs you may create/obtain. There
+are none provided with this release.
+
+
+-- Contact Info
+
+If you have questions, suggestions or problems specifically with
+the OS/2 VAC++ port of Python, please contact me at:
+
+ Jeff Rush <jrush@summit-research.com>.
+
+I support no other platform but OS/2 (and eventually AmigaDOS).
