changeset 5959:a34cb5eb18ca draft

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
(svn r8631) -Add: added parameter -l ip[:port] to ./openttd, which redirects DEBUG() to a remote connection over TCP For example, launch on 192.168.0.1 with, say, netcat a listener: netcat -l -p 3982 Launch OpenTTD on a remote host (say, PSP): ./openttd -l 192.168.0.1 -d9 And you get all debug information on 192.168.0.1. Very useful for debugging Portable systems.
