+      To build the parser, very <emphasis>recent</emphasis> versions
+      of Bison and Flex are required.  (This is because Nix needs GLR
+      support in Bison and reentrancy support in Flex.)  For Bison,
+      you need version 1.875c or higher (1.875 does
+      <emphasis>not</emphasis> work), which can be obtained from the
+      <ulink url='ftp://alpha.gnu.org/pub/gnu/bison'>GNU FTP
+      server</ulink>.  For Flex, you need version 2.5.31, which is
+      available on <ulink
+      url='http://lex.sourceforge.net/'>SourceForge</ulink>.  Slightly
+      older versions may also work, but ancient versions like the
+      ubiquitous 2.5.4a won't.  Note that these are only required if
+      you modify the parser or when you are building from the
