# Helper to bypass AC_ERLANG_CHECK_LIB
#
# Ejabberd releases do not download specific versions of its erlang
# dependencies. Instead, it clones the master branch of a git
# repository and asks erl to provide the library version. However,
# the target erl program cannot be called from the host. So, this
# script aims at finding the library version installed on the target,
# without calling erlang.
usage() {
cat <<EOF
Usage:
$0 library
Look for Erlang's library in TARGET_DIR/usr/lib/erlang/lib.
If the library is found, it returns the path to the latest version,
relative to TARGET_DIR. Otherwise, it returns "not found".
If there are several versions, it returns an error because it does not
know which one Erlang uses.
