gen_html - a program for automatic generation of zstd manual

This simple C++ program generates a single-page HTML manual from zstd.h.

The format of recognized comment blocks is following:

comments of type /*! mean: this is a function declaration; switch comments with declarations
comments of type /** and /*- mean: this is a comment; use a <H2> header for the first line
comments of type /*= and /**= mean: use a <H3> header and show also all functions until first empty line
comments of type /*X where X is different from above-mentioned are ignored

Moreover:

ZSTDLIB_API is removed to improve readability
typedef are detected and included even if uncommented
comments of type /**< and /*!< are detected and only function declaration is highlighted (bold)

The program requires 3 parameters:

gen_html [zstd_version] [input_file] [output_html]

To compile program and generate zstd manual we have used:

make
./gen_html.exe 1.1.1 ../../lib/zstd.h zstd_manual.html
