Starting with http://www.bunkus.org/videotools/mkv...0081006-12.rar all EXEs have VERSIONINFO resources. Here's such a resource for mkvmerge for a release version:

1 VERSIONINFO
 FILEVERSION 2, 3, 0, 0
 PRODUCTVERSION 2, 3, 0, 0
 FILEFLAGSMASK 0x3f
 FILEOS 0x4
BEGIN
  BLOCK "StringFileInfo"
  BEGIN
    BLOCK "040904B0"
    BEGIN
      VALUE "CompanyName", "Moritz Bunkus"
      VALUE "FileDescription", "mkvmerge"
      VALUE "FileVersion", "2.3.0"
      VALUE "InternalName", "mkvmerge"
      VALUE "LegalCopyright", "Released under the GNU Pulic License http://www.gnu.org/licenses/gpl-2.0.html"
      VALUE "OriginalFilename", "mkvmerge"
      VALUE "ProductName", "MKVToolNix"
      VALUE "ProductVersion", "2.3.0"
    END
  END
END

Builds between releases have their build date and number coded into "File Version" and "Product Version", e.g.

...
      VALUE "FileVersion", "2.3.0-build20081006-12"
