# install-dependencies.ps1 - Install Windows dependencies for building Mercurial

# Copyright 2019 Gregory Szorc <[e-mail]>
#
# This software may be used and distributed according to the terms of the
# GNU General Public License version 2 or any later version.

# This script can be used to bootstrap a Mercurial build environment on
# Windows.
#
# The script makes a lot of assumptions about how things should work.
# For example, the install location of Python is hardcoded to c:\hgdev\*.
#
# The script should be executed from a PowerShell with elevated privileges
# if you don't want to see a UAC prompt for various installers.
#
# The script is tested on Windows 10 and Windows Server 2019 (in EC2).
