jrlopezp has created two tools to assist with the creation of semaphore files, a system tray tool and a command line tool.
The system tray version now supports command lines options, so this is likely the best solution.
Release Notes:
[July/02/2005 – 1.3.0.0]
the program now accepts command switches for the creation of the semaphore files so now you can create schedule batch files and take advantage of thie new feature.
example: “c:\mdsemgen /a” (assuming MDsemgen.exe is located in C:\) will create an ALIAS.SEM in the APP folder.
For a list of available switches you can type “mdsemgen /?” or “mdsemgen /help”
UPDATE (2008/06/03): Version 2.0 has been released, see the update.
