| 3 | ## This script replaces the default "erl" in erts-VSN/bin. This is necessary |
| 4 | ## as escript depends on erl and in turn, erl depends on having access to a |
| 5 | ## bootscript (start.boot). Note that this script is ONLY invoked as a side-effect |
| 6 | ## of running escript -- the embedded node bypasses erl and uses erlexec directly |
| 7 | ## (as it should). |
| 8 | ## |
| 9 | ## Note that this script makes the assumption that there is a start_clean.boot |
| 10 | ## file available in $ROOTDIR/release/VSN. |
