This should maintain compatibility with old clients with one exception - the IPC_NEWMAIL message is now in the standard format, so mixing client versions will break if this message is sent.

Processes nolonger use kill() to determine the existance of another process.  The IPC mechanism itself will take care of cleaning up the who list if clients die without cleaning it up.  The existance of another process can be determined by trying to send an IPC_NOOP message to it.

The +I special flag and corresponding IPC messages have also been removed (refs #10).

Fixed up ipc_send_to_username() so it deals with users having multiple logins (messages go to all who entries with the specified login name)

for some reason changing script_output=0 doesnt have any effect
refs #13

so you can bind them or otherwise use them anywhere you would have used a mwscript one.
the paramteter passing needs a bit of tidying up, because the way vars are passed into mwscript is utterly insane

version deployed on silver). Long past due for a merge.

Removing all scripthelp files in preparation to readd them with symlinks (svn doesn't like the change of special status when committing)

Turned the string conversion functions into wrappers around more generic functions, and added a couple more wrappers to deal with UTF-8 strings. Also check UTF-8 is available to make sure these work.

This is in preparation for changing the IPC to use UTF-8. wchar_t would probably be preferable except that its representation is allowed to be locale-dependent (though it happens to be UCS-4 for glibc).

There is now an "ison" function, please use that instead of grovelling through the who file in future.
