 ** Call this program with three arguments:
 **
 **     ./a.out manifest.uuid manifest VERSION
 **
 ** Note that the manifest.uuid and manifest files are generated by Fossil.
+**
+** The output becomes the "VERSION.h" file.  The output is a C-language
+** header that contains #defines for various properties of the build:
+**
+**   MANIFEST_UUID              These values are text strings that
+**   MANIFEST_VERSION           identify the Fossil check-in to which
+**                              the source tree belongs.  They do not
+**                              take into account any uncommitted edits.
+**
+**   FOSSIL_BUILD_HASH          A hexadecimal string that is a strong hash
+**                              of the MANIFEST_UUID together with the
+**                              current time of the build.  We normally want
+**                              this to be different on each build, as the
+**                              value is used to expire ETag: fields in
+**                              HTTP requests.  But if you need to do
+**                              repeatable byte-for-byte identical builds,
+**                              add the -DFOSSIL_BUILD_EPOCH=n option.
+**
+**   MANIFEST_DATE              The date/time of the source-code check-in
+**   MANIFEST_YEAR              in various formats.
+**   MANIFEST_NUMERIC_DATE
+**   MANIFEST_NUMERIC_TIME
+**
+**   RELEASE_VERSION            The version number (from the VERSION source
+**   RELEASE_VERSION_NUMBER     file) in various format.
+**   RELEASE_RESOURCE_VERSION
+**
+** New #defines may be added in the future.
