MCCRestart is a tool to schedule server restarts. It saves player and chunk data before each restarts at specified times or delays and gives a warning message to each players before restart. You can also give a reason for the restart. (see commands section)
If a problem occurs during restarts, post the mccrestart.log in a new issue.

In your config.yml file you can specify a batch file for the launch parameter. Example :

@echo off

set memory=512

if /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xms%memory%M -Xmx%memory%M -jar "%~dp0craftbukkit.jar"
if /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86" java -Xms%memory%M -Xmx%memory%M -jar "%~dp0craftbukkit.jar"

If the Permissions plugin is not detected, only OPs can use restart and mccrestart commands.
