#!/usr/bin/env xonsh

# A platform independent Xonsh script to build LFortran. Works on Linux, macOS
# and Windows. The prerequisites such as bison, re2c or cython must be already
# installed.
#
# Some issues (with Xonsh):
#
# * Some output seems to be lost on Windows
#   (https://github.com/xonsh/xonsh/issues/3291)
#
# * The commands that are executed are sometimes printed after the output,
#   which makes the log unreadable (https://github.com/xonsh/xonsh/issues/3293)
#
# * This script is too slow (due to https://github.com/xonsh/xonsh/issues/3064)
#   to be suitable for day to day development, but on the CI the few extra
#   seconds do not matter much
