I am looking for a way to create documentation pages in a similar style to Doxygen, but I don't want to have to put the documentation into my code as comments. The optimal way would be to instead typing that into normal text files or something and then generate the pages from that.
From what I've understood, Doxygen doesn't support this, so I am wondering if there are any alternatives out there that are able to do what I am looking for.
Create in your *.dox file in the section INPUT reference to folder where you place regular text files. For example:
INPUT = ./supplement
After that you can create regular text files just place /*! in the beginning and */ at the end. And classify it with \page or other tags for section. For example:
My.txt
/*!
\page threading Describe Threading tech
In details this describe cases:
\li case 1
\li case 2
*/
You can place multiple \page declarations in the single file (see http://www.doxygen.nl/manual/commands.html#cmdpage)
