[erlang-bugs] escript man page
Thu Aug 28 06:52:35 CEST 2008
If trap_exit is supposed to be false (which, I agree, is what I expect)
then either I have made a mistake somewhere(*), or there is a bug in
escript (not the man page).
(*) test program:
#! /usr/bin/env escript
main(_) -> io:fwrite( "~w~n", [erlang:process_info(erlang:self(),
; which escript
; uname -a
