+the @code{vparse(string)} function.  Unlike the @code{VersionNumber(string)}
+constructor, @code{vparse(string)} can handle version-number strings in a much
+wider range of formats than are encompassed by the semver standard.  This is
+useful in order to support @code{VersionNumber} comparisons applied to
+\"foreign\" version numbers from external packages.")
