# -------------------------------------------------------------------------
# Source this to build CGE build tool and expose env vars.
# Quick way to *temporarily* test CGE on given system.
#
# Sets up
# - FPC from castle-fpc in temp dir
#   (if CGE_USE_FPC is not set to "path" or "fpcupdeluxe",
#   see below)
# - and CGE in $HOME/sources/castle-engine/castle-engine
#   (could be modified to download CGE each time).
#
# Recompiles CGE build tool, adds to $PATH everything required,
# sets $CASTLE_ENGINE_PATH .
# Doesn't modify any state outside of temporary directory,
# doesn't move new build tool to ~/bin/ to avoid changing state that could
# affect others.
#
# Set CGE_USE_FPC to determine used FPC:
# - CGE_USE_FPC = path : use existing FPC on $PATH.
# - CGE_USE_FPC = fpcupdeluxe : use existing FPC on $PATH.
# - CGE_USE_FPC otherwise (or unset) : download FPC from castle-fpc in temp dir.
