#
# This script is used to quickly test a VSIX (Visual Studio Extension) file
# with Visual Studio 2015 on Windows.
#
# PREREQUISITES
#
# 1. This tool is Windows only.
#
# 2. This tool must be executed with "elevated administrator" privileges.
#
# 3. Tcl 8.4 and later are supported, earlier versions have not been tested.
#
# 4. The "sqlite-UWP-output.vsix" file is assumed to exist in the parent
#    directory of the directory containing this script.  The [optional] first
#    command line argument to this script may be used to specify an alternate
#    file.  However, currently, the file must be compatible with both Visual
#    Studio 2015 and the Universal Windows Platform.
#
# 5. The "VERSION" file is assumed to exist in the parent directory of the
#    directory containing this script.  It must contain a version number that
#    matches the VSIX file being tested.
#
# 6. The temporary directory specified in the TEMP or TMP environment variables
#    must refer to an existing directory writable by the current user.
#
# 7. The VS140COMNTOOLS environment variable must refer to the Visual Studio
#    2015 common tools directory.
#
# USAGE
#
# The first argument to this script is optional.  If specified, it must be the
# name of the VSIX file to test.
