These are various utilities to make life easier. Here's a description of each:

html_hash
----------

Written to append a ,NULL to the hash tables that can be found in
src/html_tokenizer.c

This is used when you generate a new hash table (with gperf) and then must fill
in all of the function pointers. This makes life easier by setting all of them
to NULL first so you don't have to do all of them at once to do a compile for
testing etc...

To use it copy and paste your hash table into a file called 'foo' or something.
You should only include the table itself and not the struct or anything. So an
example is this:

{"Q", Q},
{"BR",BR}

etc....

Then type:

$ ./hash_util foo

and it will dump the new table to stdout.

-----------------
color_hash
-----------------

color_hash will put the 2nd element in a hash table into quotation marks. 
Written for the colors.c hash table.
