You should either apply the patch, using the patch command (e.g.
"cd htsearch; patch < /path/to/multiboost.1" -- see "man patch" for
details on this command), or you can manually apply the patch by editing
htsearch/parser.cc and adding the two lines that have the "+" signs to
the file, putting them right between the lines of context in the patch
(lines without + signs), at line 380. Of course, you must remove the
"+" signs when you manually add the lines to the file.
The manual approach is fine for small patches like this, but if you ever
need to apply a larger patch, you'll be glad you took the time to learn
how to use the patch command.
In any case, once the parser.cc file is patched or edited, you can edit
it to change the 1000 to the config.Value expression below if you want
the factor to be configurable at run time.
