The version is listed - but can't change the title of this thread.
The link to the old code which this is a modification of has the original readme file. I'm too lazy to put one out myself - I have done enough just maintaining this thing for FGU and my own uses. As far as version numbers on the file - NEVER. I use no version numbers on any extension I work with so I never risk having two versions of the same thing in my extension folder. DMsG evidently messes up my non version delivered filename for extensions in my other stuff and I can't prevent that - though I never suffer from it as I deliver the non versioned filename off of my machine which is what I have locally and store locally. The only time I version number an .ext file is when I save it off in the old version folder after a modification.
So readme? I'm fine if you want to update one with all the latest stuff and version changes and post it here like someone did with compatibility modifications, I'll add it to page 1. But the way its delivered is without a version number on the filename. Filenames are meaningless anyway its the extension.xml that defines all the properties - and I for sure don't want to have to manage which file version is in the extensions folders. There is only ever one. The active latest and greatest. And when the next one comes along - its going to stomp over the old version and STILL be the latest and greatest.
As I have very strong feelings on versions in the filenames creating them as unique files when I don't want them to be unique files - that won't be happening :)
