# This shell fragment is intended for use in `bash` or `zsh`. While it
# may work in other shells it is not meant to, and any misbehaviour is not
# considered a bug in that case.
#
# NetSurf Library, tool and browser development support script
#
# Copyright 2013-2024 Vincent Sanders <vince@netsurf-browser.org>
# Released under the MIT Licence
#
# This script allows NetSurf and its libraries to be built without
# requiring installation into a system.
#
# Usage: source env.sh
#
# Controlling variables
# HOST sets the target architecture for library builds
# BUILD sets the building machines architecture
# TARGET_WORKSPACE is the workspace directory to keep the sandboxes
# TARGET_TOOLKIT controls development package installs
# can be unset or one of framebuffer, gtk2, gtk3, qt6
#
# The use of HOST and BUILD here is directly comprable to the GCC
# usage as described at:
# http://gcc.gnu.org/onlinedocs/gccint/Configure-Terms.html
