// Program Version / Release Number
// - Format: "X.Y.Z"          - (full public release)
// - Format: "X.Y.Z (beta W)" - (beta release)
// - Note that when the version number is incremented, I need
//   to also update the corresponding version numbers in the
//   JPEGsnoop.rc resource under "Version.VS_VERSION_INFO".

// Version number for the database signatures
// - This version number has been provided in case I decide
//   to change the database format. If a change to the format is
//   required, then I can use this version number to help build a
//   converter/import routine.

// - The URLs that are used to indicate new release availability are also
//   provided here. These pages have specific formatting that JPEGsnoop
//   parses to identify if a newer version is available.
