Take a whack at providing some texinfo style docs. Mostly it's just basic "how 2 write sane dox" stuff. git-svn-id: svn://svn.berlios.de/openocd/trunk@2270 b42882b7-edfa-0310-969c-e2dbd0fdcd60

/** @page styletexinfo Texinfo Style Guide
-This page needs to provide style guidelines for Texinfo, the mark-up
-language used by The Guide for OpenOCD Users.
+The User's Guide is there to provide two basic kinds of information. It
+is a guide for how and why to use each feature or mechanism of OpenOCD.
+It is also the reference manual for all commands and options involved
+in using them, including interface, flash, target, and other drivers.
+At this time, it is the only user-targetted documentation; everything
+else is addressing OpenOCD developers.
+
+There are two key audiences for the User's Guide, both developer based.
+The primary audience is developers using OpenOCD as a tool in their
+work, or who may be starting to use it that way. A secondary audience
+includes developers who are supporting those users by packaging or
+customizing it for their hardware, installing it as part of some software
+distribution, or by evolving OpenOCD itself. There is some crossover
+between those audiences. We encourage contributions from users as the
+fundamental way to evolve and improve OpenOCD. In particular, creating
+a board or target specific configuration file is something that many
+users will end up doing at some point, and we like to see such files
+become part of the mainline release.
+
+General documentation rules to remember include:
+
+- Be concise and clear. It's work to remove those extra words and
+ sentences, but such "noise" doesn't help readers.
+- Make it easy to skim and browse. "Tell what you're going to say,
+ then say it". Help readers decide whether to dig in now, or
+ leave it for later.
+- Make sure the chapters flow well. Presentations should not jump
+ around, and should move easily from overview down to details.
+- Avoid using the passive voice.
+- Address the reader to clarify roles ("your config file", "the board you
+ are debugging", etc.); "the user" (etc) is artificial.
+- Use good English grammar and spelling. Remember also that English
+ will not be the first language for many readers. Avoid complex or
+ idiomatic usage that could create needless barriers.
+- Use examples to highlight fundamental ideas and common idioms.
+- Don't overuse list constructs. This is not a slide presentation;
+ prefer paragraphs.
+
+When presenting features and mechanisms of OpenOCD:
+
+- Explain key concepts before presenting commands using them.
+- Tie examples to common developer tasks.
+- When giving instructions, you can \@enumerate each step both
+ to clearly delineate the steps, and to highlight that this is
+ not explanatory text.
+- When you provide "how to use it" advice or tutorials, keep it
+ in separate sections from the reference material.
+- Good indexing is something of a black art. Use \@cindex for important
+ concepts, but don't overuse it. In particular, rely on the \@deffn
+ indexing, and use \@cindex primarily with significant blocks of text
+ such as \@subsection. The \@dfn of a key term may merit indexing.
+- Use \@xref (and \@anchor) with care. Hardcopy versions, from the PDF,
+ must make sense without clickable links (which don't work all that well
+ with Texinfo in any case). If you find you're using many links,
+ read that as a symptom that the presentation may be disjointed and
+ confusing.
+- Avoid font tricks like \@b, but use \@option, \@file, \@dfn, \@emph
+ and related mechanisms where appropriate.
+
+For technical reference material:
+
+- It's OK to start sections with explanations and end them with
+ detailed lists of the relevant commands.
+- Use the \@deffn style declarations to define all commands and drivers.
+ These will automatically appear in the relevant index, and those
+ declarations help promote consistent presentation and style.
+ - It's a "Command" if it can be used interactively.
+ - Else it's a "Config Command" if it must be used before the
+ configuration stage completes.
+ - For a "Driver", list its name.
+ - Use BNF style regular expressions to define parameters:
+ brackets around zero-or-one choices, parentheses around
+ exactly-one choices.
+ - Use \@option, \@file, \@var and other mechanisms where appropriate.
+ - Say what output it displays, and what value it returns to callers.
+ - Explain clearly what the command does. Sometimes you will find
+ that it can't be explained clearly. That usually means the command
+ is poorly designed; replace it with something better, if you can.
+ - Be complete: document all commands, except as part of a strategy
+ to phase something in or out.
+ - Be correct: review the documentation against the code, and
+ vice versa.
+- Alphabetize the \@defn declarations for all commands in each
+ section.
+- Keep the per-command documentation focussed on exactly what that
+ command does, not motivation, advice, suggestions, or big examples.
+ When commands deserve such expanded text, it belongs elsewhere.
+ Solutions might be using a \@section explaining a cluster of related
+ commands, or acting as a mini-tutorial.
+- Details for any given driver should be grouped together.
+
+The User's Guide is the first place most users will start reading,
+after they begin using OpenOCD. Make that investment of their time
+be as productive as possible. Needing to look at OpenOCD source code,
+to figure out how to use it is a bad sign, though it's OK to need to
+look at the User's guide to figure out what a config script is doing.
