# esy-configure
#
# Wrapper to delegate to configuration to the
# appropriate `configure` strategy based on the active platform.
#
# Today, OCaml has separate build strategies:
# - Linux, OSX, Cygwin (gcc) -
# https://github.com/ocaml/ocaml/blob/trunk/INSTALL.adoc
# - Windows, Cygin (mingw) -
# https://github.com/ocaml/ocaml/blob/trunk/README.win32.adoc
#
# We want `esy` to work cross-platform, so this is a shim script that
# will delegate to the appropriate script depending on the
# platform. We assume that if the platform is `CYGWIN` that the
#`mingw` (native executable) strategy is desired.
