% Modify docstrip. A pseudo-guard is defined to set variables:
% <<name=value>>. These variables are used with <@name@> Two further
% pseudo-guards define "block" variables: <<*name>> and <</name>>
% delimite the lines to be retrieved with <@name@>. Note the verbatim
% guard is overridden, but it's not used here.  This is done in two
% passes: 1) with saving true, there is a dummy pass, generating
% nothing, but blocks are read and saved; 2) with saving false, blocks
% are always ignored, but replacing <@name@>.  While <@name@> can be
% used freely outside <<>>, it's only allowed inside <<>> if
% previously defined. Deeper nesting is not allowed.
