## 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.
