rem
rem  This script performs several maintenance functions prior to building
rem  simh projects.  Some of these funtions are optional and depend on the
rem  needs of the project being built, and others are generic and are always
rem  performed.
rem
rem  The optional activities are invoked by passing parameters to this 
rem  procedure.  The parameters are:
rem     ROM     To run the BuildROMs program prior to executing a project
rem             build.  This program verifies that the include files containing
rem             ROM images are consistent with the ROM images from which they
rem             are derived.
rem     BUILD   To validate that the required dependent libraries and include
rem             files are available in the directory ..\..\windows-build\
rem             These libraries currently include winpcap and pthreads and 
rem             optionally SDL and LIBPCRE.
rem     LIBSDL  To validate that the required dependent SDL libraries and include
rem             files are available in the directory ..\..\windows-build\
rem     LIBPCRE To validate that the required dependent PCRE libraries and include
rem             files are available in the directory ..\..\windows-build\
rem
rem  In addition to the optional activities mentioned above, other activities
rem  are also performed.  These include:
rem       - confirming that if the current source is a clone of the simh
rem         git repository, then then git hooks which manage making the
rem         git commit hash available during builds are properly installed
rem         in the repository hooks directory.  When the githooks are installed
rem         the current commit id is generated if git.exe is available in the
rem         current path.
rem       - performing the activities which make the git repository commit id
rem         available in an include file during compiles.
rem       - Converting Visual Studio Projects to a form which will produce 
rem         binaries which run on Windows XP if the current build environment 
rem         supports it and the correct components are installed.
rem         This activity is triggered by the first argument being the name
rem         of a the current Visual Studio project file.  This argument MUST 
rem         only be provided on a single project which invokes this procedure
rem         AND that project should be one which all other projects in a 
rem         solution are dependent on.
