 # We combine the build and patch into a single entry since
 # the windows installer does _not_ consider a change in Patch
 # to require a new install.
 # In addition to that, the limits on the size are:
 # Major: 256
 # Minor: 256
-# Build: 65536
+# Patch: 65536
 # To circumvent this we create the version like this:
 #   Major.Minor.X
-# where X is Build<<9 + Patch
-# Example version 1.2.4.14 will go to 1.2.2062
+# from "major.minor.patch-prerelease.prerelease_patch"
+# where X is "patch<<10 + prerelease<<5 + prerelease_patch"
+# Example version 1.2.4-dev.2.3 will go to 1.2.4163
