CCZE is able to toggle some of its features with this option. You can toggle the scroll, wordcolor, lookups, and transparent features, or you can fiddle with cssfile. All of these are enabled by default, except cssfile. One can turn them off by prefixing the option with a "no".
With scroll, one can enable or disable scrolling. If the output is not redirected, it is wise to leave it enabled.
The wordcolor option makes ccze search for different keywords in unparsed input, and color those too. Since it is quite fast, and makes the output look better, it is recommended to leave this enabled.
However, lookups is an option that might be better to disable. When on, ccze will try to look up usernames, service names, and lots of other stuff, which will slow down coloring a great deal. If one is piping a long log through ccze, this option might be turned off to speed up the process.
With the transparent option, one can make CCZE treat black background colors as transparent - that means, a black background will appear transparent in a similar X terminal. If turned off, it will appear as black.
If cssfile is set, then CCZE will not inline the Cascading Style Sheet information into the outputted HTML, but include a link to the external stylesheet given in this parameter.
