[s3;:1: 1. Introduction&]
[s5; Topic`+`+ is a documentation system designed for U`+`+, but 
usable for any project. Its main purpose is to make dealing with 
application related documents as easy as possible. It can be 
used to provide RichText resources for applications (including 
help), to prepare printed manuals and also to document code. 
Most documents you have encountered when dealing with U`+`+ were 
created and managed using Topic`+`+ (including the website).&]
[s5; Topic`+`+ documents (usually called just `"topics`") are organized 
in topic groups that are parts of packages. They are logically 
divided in several groups `- some group names are standardized, 
`"src`" should contain code`-reference, `"srcdoc`" is for other 
code`-related documents, `"app`" are document resources for applications.&]
[s5; U`+`+ library is capable of including topics into target executable 
and exploiting them in user code. To see how this can be done, 
see `"Topic`" reference example.&]
[s3;:2: 2. Basics&]
[s5; To create a new topic group, right`-click in the lower left 
pane of TheIDE, where package files are listed. From context 
menu, choose [/ Insert package directory file(s) ]as if you open/create 
any other file. To path write the group name with .tpp extension, 
e.g. `"app.tpp`". Now press enter or click on [/ Open ]and Topic 
editor with new group will appear. Now you have to add some topic 
to it. Right click in the topic listing area (see the picture 
in next paragraph). In the dialog that comes up you choose a 
name for the topic and its language. You can also include a template, 
which contains some predefined styles.&]
[s5; The actual process of writing the docs is very similar to writing 
anything in common rich text editor. You can add hyperlinks to 
any other documentation topic as well as to the Internet. You 
can add tables, images, use various fonts and colors or even 
define paragraph styles to make the editing really simple. You 
can also add code reference, to associate given paragraph with 
a piece of code which can then be accessed from the documentation.&]

[s5; Topic`+`+ is directly connected with [^topic`:`/`/ide`/app`/Assist`$en`-us^ Assist
`+`+] system to create and provide documentation of code elements. 
Each paragraph of topic can be connected with one code element 
using the paragraph label (F in Topic`+`+ window description). 
This label contains unique code element signature `- this way 
the paragraph can be connect with unambiguous code element.&]
[s5; There are two ways how to document a code element. Either directly 
from code editor or from Topic`+`+ editor.&]

[s5; [/ This paragraph is aimed at curious readers, who are interested 
in the inner machinery behind Topic`+`+. Feel free to skip it 
if you want.]&]
[s5; Each topic group is represented on hard drive as a directory, 
e.g. (uppsrc/Core/srcdoc.tpp/) which contains one `*.tpp file 
for every topic. All `*.tpp files are internally just a text 
file in [^topic`:`/`/RichText`/srcdoc`/QTF`$en`-us^ QTF] format 
(U`+`+ specific rich formatted text format). TheIDE also creates 
`"inclusion file`" with .tppi extension for each topic and all.i 
file for each group. These files are useful for easy embedding 
the documentation into application (See the above mentioned `"Topic`" 
reference package). ]]
