I'm using vc7.1. I'd like to set JAMSHELL to something that calls
cmd.exe which can execute a script. We have a very funny way of
executing commands on a remote host: create a script runme.cmd in some
folder via a samba share, and rename it to run.cmd. That triggers a
program running on that host to execute it.
If bjam always produces a .bat file for multi-line actions, then I'd be
happy to take that batch file as a parameter to my script, and make that
execute on a remote host. But currently, that seems to be impossible if
multiline-commands are always executed directly instead of via JAMSHELL.
Is it difficult to implement this behaviour as a new feature in bjam?
