+       dupargv -- duplicate an argument vector
+
+SYNOPSIS
+
+       char **dupargv (vector)
+       char **vector;
+
+DESCRIPTION
+
+       Duplicate an argument vector.  Simply scans through the
+       vector, duplicating each argument argument until the
+       terminating NULL is found.
+
+RETURNS
+
+       Returns a pointer to the argument vector if
+       successful. Returns NULL if there is insufficient memory to
+       complete building the argument vector.
