The inc files that have been removed were from the days, prior to
commit 97f6da1247 when the web site
used left side links and right side content. Now, no web IOCCC
web pages use them so there have been removed so as to not
needlessly complicate the `inc/` directory with unused stuff.
inc
The inc directory holds content that is used by the tools in the bin directory.
Why the name inc?
We use inc because "include" would be misleading for both C and because the contents of HTML files under inc are not really included by the web server or the browser. Content of HTML files is processed by tools the bin directory. Processing can include substitution of strings of the form %%CURDS%% with some command line supplied value by the tool in question.
