adding build number or time stamp to outfile

[mancini]

Normally it is usefull if some kind of unique string can be added to name of the installer like a build date or number

i tried
OutFile "installer${__TIME__}.exe"
but it contains a space and i would really like to keep track of build numbers intead

i am now investingating making a batch script that would create a file with a number , incrementing it every time it is runned , then running makensis , and reading from the nsi script the number file then appending the number to outfile

any other sugestions ?
would the developers think they can implement something in the lines of this ?
