       Specify a string that identifies your package. You may wish to include
       a build number or build date. This version string will be included in
       the output of gcc --version, and also in binutils, eglibc, gdb and
       gdbserver.
 
+      If this string is left empty, the actual package version will be:
+          "crosstool-NG ${CT_VERSION}"
+      Otherwise, it will be:
+          "crosstool-NG ${CT_VERSION} - ${CT_TOOLCHAIN_PKGVERSION}"
+
       This is passed to the configure flag --with-pkgversion.
