+  * **Include completed PDF** and add page numbers and other headings: ''\usepackage{pdfpages}''<code>
+    % settings
+    \markright{Author Name}    % or e.g. package fancyhdr
+    \setcounter{page}{13}      % number of first page
+    % inserting (first page with pagenumber in the foot, others in the head with author name)
+    \includepdf[pages=1, pagecommand={\thispagestyle{plain}}]{file.pdf}
+    \includepdf[pages=2-, pagecommand={\thispagestyle{myheadings}}]{file.pdf}</code>
+  * ''\textwidth'', ''\linewidth'', ''\columnwidth'', ''\hsize'' and others explained [[http://tex.stackexchange.com/questions/16942/difference-between-textwidth-linewidth-and-hsize|here]] (You want ''\linewidth'' in most cases.)
+  * Useful **packages**:
+    * Source printing: //''fancyvrb''//, //''listings''//
+    * //''fancyhdr''//
+    * pseudocode //''algorithmicx''//
+    * trees: //''xytree''// (complicated), //''dtree''// (Obo, pstricks), //''xyling''// (Martin P., ''\B'' and ''\T'' must be relaxed)
+    * tables: //''xtab''// (better than ''longtable'' or ''supertabular''), //''tabulary''// (pretty wrapped text in autosized cells, similar to ''tabularx''), //''booktabs''// (no vertical lines, ''\toprule'', ''\midrule'', ''\bottomrule'' instead of ''\hline'') (all from this [[www.tug.org/pracjourn/2007-1/mori/mori.pdf|compendium]])
+  * ''longtable'' or ''xtabular'' environment **cannot** be inside ''table'' environment. (Put it inside ''center'' instead, since you cannot use ''\centering'' as before.)
+  * ''hyperref'' package:
+    * If some **links from ToC** point to **incorrect** objects (e.g. section III.2.5 points to the page where the section I.2.5 starts), then the problem is in internal hyperref naming convention (both section in the example are represented as 'section.2.5'). You can change it either by
+      * ''naturalnames=true'' (=> 'section.III.2.5'), or
+      * ''hypertexnames=false'' (=> 'section.289')
+==== počítání slov (a dalších věcí) ====
+<code>texcount soubor.tex</code>
+''texcount -inc soubor.tex'' ... započítá správně slova i v souborech vložených v hlavním souboru pomocí ''\include''
+Podrobnosti v dokumentaci: ''texdoc texcount''
