- ## This script replaces the default "erl" in erts-VSN/bin. This is necessary
- ## as escript depends on erl and in turn, erl depends on having access to a
- ## bootscript (start.boot). Note that this script is ONLY invoked as a side-effect
- ## of running escript -- the embedded node bypasses erl and uses erlexec directly
- ## (as it should).
- ##
- ## Note that this script makes the assumption that there is a start_clean.boot
- ## file available in $ROOTDIR/release/VSN.
- # Determine the abspath of where this script is executing from.
- ERTS_BIN_DIR=$(cd ${0%/*} && pwd)
- # Now determine the root directory -- this script runs from erts-VSN/bin,
- # so we simply need to strip off two dirs from the end of the ERTS_BIN_DIR
- # path.
