//
// Config.pp
//
// This file defines certain configuration variables that are written
// into the various make scripts.  It is processed by ppremake (along
// with the Sources.pp files in each of the various directories) to
// generate build scripts appropriate to each environment.
//
// ppremake is capable of generating makefiles for Unix compilers such
// as gcc or SGI's MipsPRO compiler, as well as for Windows
// environments like Microsoft's Visual C++.  It can also,
// potentially, generate Microsoft Developer's Studio project files
// directly, although we haven't written the scripts to do this yet.
// In principle, it can be extended to generate suitable build script
// files for any number of different build environments.
//
// All of these build scripts can be tuned for a particular
// environment via this file.  This is the place for the user to
// specify which external packages are installed and where, or to
// enable or disable certain optional features.  However, it is
// suggested that rather than modify this file directly, you create a
// custom file in your home directory and there redefine whatever
// variables are appropriate, and set the environment variable
// PPREMAKE_CONFIG to refer to it.  In this way, you can easily get an
// updated source tree (including a new Config.pp) without risking
// accidentally losing your customizations.  This also avoids having
// to redefine the same variables in different packages (for instance,
// in dtool and in panda).
//
// The syntax in this file resembles some hybrid between C++
// preprocessor declarations and GNU make variables.  This is the same
// syntax used in the various ppremake system configure files; it's
// designed to be easy to use as a macro language to generate
// makefiles and their ilk.
// 

// Some of the variables below are defined using the #define command,
// and others are defined using #defer.  The two are very similar in
// their purpose; the difference is that, if the variable definition
// includes references to other variables (e.g. $[varname]), then
// #define will evaluate all of the other variable references
// immediately and store the resulting expansion, while #defer will
// store only the variable references themselves, and expand them when
// the variable is later referenced.  It is very similar to the
// relationship between := and = in GNU Make.
//
// In general, #defer is used in this file, to allow the user to
// redefine critical variables in his or her own Config.pp file.




// What kind of build scripts are we generating?  This selects a
// suitable template file from the ppremake system files.  The
// allowable choices, at present, are:
//
//  unix      - Generate makefiles suitable for most Unix platforms.
//  msvc      - Generate makefiles suitable for building on Windows platforms
//              (e.g. Windows NT, Windows 2000) using the Microsoft Visual C++
//              command-line compiler and Microsoft nmake.
//  gmsvc     - Generate makefiles similar to the above, using Microsoft
//              Visual C++, but uses the Cygwin-supplied GNU make
//              instead of Microsoft nmake.  This is potentially
//              faster if you have multiple CPU's, since it supports
//              distributed make.  It's a tiny bit slower if you're
//              not taking advantage of distributed make, because of
//              the overhead associated with Cygwin fork() calls.
