Radical proposalsymfony#1: focus more specifically on creating pages in this document and put related (but not precisely 'dependent') discussions of directories, bundles and environments in a separate document called Structuring a Symfony App. Radical proposalsymfony#2: take a heavy axe to The Book to eliminate every description, explanation and detail that's not at the highest possible altitude. Replace extraneous detail with links to the deeper information elsewhere, e.g. Best Practices. The ideal outcome would be DRYer docs and an easier to read and maintain The Book.Keep in mind that I'm a person with 'fresh eyes' vs one with a clear understanding of all objectives that must be met on this introductory page. I expect the best course is something between what I propose and what is currently there.That said, this revision takes an initial stab, so please feel free to use or ignore as you see fit.

I've made most, but not all, of the changes proposed by reviewers.Specifically, I haven't changed the occurrences of `we` by `you`. The reason is that it's too much work. The original PR (submitted 8 months ago) died for that reason. So here it is my question: could we bypass the `we -> you` changes to merge it as soon as possible and fix that in further pull requests?Commits-------bca9bae Updated doc references in the map.rst.inc file108f109 Removed the numbers from the file namesdb9fa43 Made a lot of improvements suggested by reviewers126bcef removed external references alignement13a7170 made some changes to better integrate the tutorial into the current documentationbf9c871 fixed markupd44e4a2 added the new tutorial in the main index73cd243 added the "Create your own framework" tutorial409dba5 move things aroundf303b20 removed versions when adding Symfony component with Composer55f5c12 updated the whole book (changes mainly related to Composer)842e4d1 bug#25 Update part06.rst (revollat)a1336e0 Update part06.rstd802d42 updated code for Symfony 2.3 and made minor tweaks to the textf3c151c reworded slightly some sentence to convert the text from a series of articles to a bookca9d5d8 removed unused references249b704 added missing linksf6656e4 removed a note that is not relevant anymore10e2732 added an index filec88c20a removed usage of the ClassLoader component in favor of Composer2ddd8b9 merged branch bamarni/master (PR#24)799e963 updated composer autoload path91e46f6 removed the paragraph about CS as we now have standards43e2e35 Merge pull request#23 from dirkaholic/master6e01599 Fix little typoe8c19f7 Merge pull request#22 from ubick/master8e7106d Fixed a typo in part02.rst (<php changed to <?php)c087780 merged branch amitayh/master (PR#17)0d6beb1 merged branch pedrotgimenez/part11 (PR#21)60617d7 Fixed one typo.aae0705 fixed CS9533f9a merged branch hrbonz/part12_fixes (PR#19)d0ff8bc updated titles400c087 add framework code as people would probably modify it following first code example (putting object creations in src/Simplex/Framework.php)de69a87 HttpKernel name can't be imported twice, if importing only Symfony\Component\HttpKernel\HttpKernel there will be problems later with HttpKernel subclasses (HttpKernel\Controller\ControllerResolver first and the others following).

IMHO, rulesymfony#1 should be applied instead of rulesymfony#2, because URI and IP match is enough for rulesymfony#1.
