I have been looking for a way to create a PEAR package out of my Symfony plugin on Windows. I am unable to find any utility or tutorial explaining the process.
In case there is no solution, I will have to manually prepare my package.xml, which is kind of sad in this world of automation.
I always use the PEAR_PackageFileManager2 for that task. It works on windows too. All you need to do is some finetunig afterwards.
