for example:

(at the root directory of your source project)
$ gtags # make tag files(GPATH,GTAGS,GRTAGS)
$ htags # make hypertext(HTML/)

Then you will find a directory named `HTML' in the current directory.

Htags has rich options. If you are new on htags then you are recommended to use the `--suggest' option. This option makes some popular options effective, and invokes gtags(1) if there is no tag files.


$ htags --suggest

If HTTP server is available then the -D and -f option are also useful.
