going on in the docs folder.

docs/README.txt

+This "package" is just a copy of the stuff I use to generate the documentation 
+for the dlib library.  It contains a copy of the XSLT and XML I use to 
+generate the HTML documentation.
+
+The current version of these files can be obtained from the dlib subversion 
+repository at: https://dclib.svn.sourceforge.net/svnroot/dclib/trunk/docs
+
+======================== Overview  ========================
+
+I write all my documentation in XML files.  If you look through the files in 
+the docs folder you will see each of them.  There is also a stylesheet.xsl 
+file which contains all the XSLT I wrote to transform XML files into HTML.  
+Anyway, I use that stylesheet to generate the dlib documentation from those 
+XML files.  
+
+There is also a stylesheet inside the docs/chm folder (htmlhelp_stylesheet.xsl) 
+that knows how to look at the XML files and generate the table of contents 
+files needed by the htmlhelp tool (the thing that makes chm help files).  
+
+======================== Installing the required tools ========================
+
+To begin with, the XML and XSLT is usable on any operating system, however, 
+all the scripts I have in the docs folder that automate everything are bash 
+shell scripts.  I also use stuff like wine and other Linux tools and I have 
+only ever tested any of this in Debian.  So if you want to use all the scripts 
+then you should probably run this stuff in Linux.  But if not you can probably 
+hack something together :)
+
+There are four scripts in the docs folder.  
+
+ - testenv:  This script tests your environment for all the needed utilities.
+	     Run it and it should tell you what else you need to install. 
+	     Note that the htmlify utility is something I wrote and is in
+	     the htmlify subfolder.  You should build and install it. 
+	     (go into that folder, make a subfolder called build, then cd
+	     into build and say:  "cmake ..; make; sudo make install".  
+	     You will need to install cmake if you don't have it already)
+
+ - makedocs: This remakes all the HTML documentation by pulling files out
+ 	     of the dlib repository.  If you want to use this stuff for your
+	     own projects you will need to edit this file a bit.
+	     
+	     Note that this script puts its output in the docs/web and
+	     docs/chm/docs folders.  I use the chm folder for off-line 
+	     documentation while the web folder contains what goes onto 
+	     dclib.sourceforge.net.  Both sets of HTML are generated from
+	     the same XML files and are mostly the same.  You will see
+	     <chm></chm> and <web></web> tags inside the XML though in 
+	     cases where the two differ.
+	
+ - makesnapshot and makerel: These run makedocs as well as create tar and
+ 	     zip files of the project.  They also run htmlhelp in wine to
+	     generate the chm help files.  Note that you will need to run
+	     docs/chm/htmlhelp/setup_htmlhelp.sh before it will work in wine.
