 :: Multi-Platform Build Tool for MSVC
 ::

 REM
 REM This batch script is used to build the SQLite DLL for multiple platforms
 REM and configurations using MSVC.  The built SQLite DLLs, their associated
 REM import libraries, and optionally their symbols files, are placed within
 REM the directory specified on the command line, in sub-directories named for
 REM their respective platforms and configurations.  This batch script must be
 REM run from inside a Visual Studio Command Prompt for the desired version of
 REM Visual Studio ^(the initial platform configured for the command prompt does
 REM not really matter^).  Exactly one command line argument is required, the
 REM name of an existing directory to be used as the final destination directory
 REM for the generated output files, which will be placed in sub-directories
 REM created therein.  Ideally, the directory specified should be empty.
 REM
 REM Example:
 REM
 REM                        CD /D C:\dev\sqlite\core
 REM                        tool\build-all-msvc.bat C:\Temp
 REM
 REM In the example above, "C:\dev\sqlite\core" represents the root of the
 REM source tree for SQLite and "C:\Temp" represents the final destination
 REM directory for the generated output files.
 REM
 REM There are several environment variables that may be set to modify the
 REM behavior of this batch script and its associated Makefile.  The list of
 REM platforms to build may be overriden by using the PLATFORMS environment
 REM variable, which should contain a list of platforms ^(e.g. x86 x86_amd64
 REM x86_arm^).  All platforms must be supported by the version of Visual Studio
 REM being used.  The list of configurations to build may be overridden by
 REM setting the CONFIGURATIONS environment variable, which should contain a
 REM list of configurations to build ^(e.g. Debug Retail^).  Neither of these
 REM variable values may contain any double quotes, surrounding or embedded.
 REM Finally, the NCRTLIBPATH and NSDKLIBPATH environment variables may be set
 REM to specify the location of the CRT and SDK, respectively, needed to compile
 REM executables native to the architecture of the build machine during any
 REM cross-compilation that may be necessary, depending on the platforms to be
 REM built.  These values in these two variables should be surrounded by double
 REM quotes if they contain spaces.
 REM
 REM Please note that the SQLite build process performed by the Makefile
 REM associated with this batch script requires both Gawk ^(gawk.exe^) and Tcl
 REM 8.5 ^(tclsh85.exe^) to be present in a directory contained in the PATH
 REM environment variable unless a pre-existing amalgamation file is used.

	REM This batch script is used to build the SQLite DLL for multiple platforms
	REM and configurations using MSVC. The built SQLite DLLs, their associated
	REM import libraries, and optionally their symbols files, are placed within
	REM the directory specified on the command line, in sub-directories named for
	REM their respective platforms and configurations. This batch script must be
	REM run from inside a Visual Studio Command Prompt for the desired version of
	REM Visual Studio ^(the initial platform configured for the command prompt does
	REM not really matter^). Exactly one command line argument is required, the
	REM name of an existing directory to be used as the final destination directory
	REM for the generated output files, which will be placed in sub-directories
	REM created therein. Ideally, the directory specified should be empty.
	REM
	REM Example:
	REM
	REM CD /D C:\dev\sqlite\core
	REM tool\build-all-msvc.bat C:\Temp
	REM
	REM In the example above, "C:\dev\sqlite\core" represents the root of the
	REM source tree for SQLite and "C:\Temp" represents the final destination
	REM directory for the generated output files.
	REM
	REM There are several environment variables that may be set to modify the
	REM behavior of this batch script and its associated Makefile. The list of
	REM platforms to build may be overriden by using the PLATFORMS environment
	REM variable, which should contain a list of platforms ^(e.g. x86 x86_amd64
	REM x86_arm^). All platforms must be supported by the version of Visual Studio
	REM being used. The list of configurations to build may be overridden by
	REM setting the CONFIGURATIONS environment variable, which should contain a
	REM list of configurations to build ^(e.g. Debug Retail^). Neither of these
	REM variable values may contain any double quotes, surrounding or embedded.
	REM Finally, the NCRTLIBPATH and NSDKLIBPATH environment variables may be set
	REM to specify the location of the CRT and SDK, respectively, needed to compile
	REM executables native to the architecture of the build machine during any
	REM cross-compilation that may be necessary, depending on the platforms to be
	REM built. These values in these two variables should be surrounded by double
	REM quotes if they contain spaces.
	REM
	REM Please note that the SQLite build process performed by the Makefile
	REM associated with this batch script requires both Gawk ^(gawk.exe^) and Tcl
	REM 8.5 ^(tclsh85.exe^) to be present in a directory contained in the PATH
