# You can use http://mirrors.cdn.adacore.com/art/591c6d80c7a447af2deed1d7
# to bootstrap (then you only need core/gcc installed). Run
# > find $install_dir \( -name ld -o -name -as \) -delete
# and
# export PATH="$install_dir/bin:$PATH"
# before compiling ($install_dir should be the directory into which you
# temporarily installed gnat-gpl).
