   O bem que a violência faz é no máximo passageira.
   O mail que ela faz é permanente. Mahatma.
\endocument}
   
3. Programmable: Turing Complete.
   More:
   1. Define new command:
      \newcommand{\mynewcommand}[3]%%Number of parameters
{
   \textbf{#1}:%First argument
   \textit{#2}:%Second argument
   \textsc{#3}:%Third argument
}
...
\mynewcommand{Bold}{Italic}{Small Caps}
      
   2. Redefining a command - must prexist!
      \renewcommand{\mynewcommand}%%You can't change number of parameters
   3. Include source files:
      \input{Chapter01/main.tex}
\input{Chapter02/main.tex}
...
\input{Chapter8/main.tex}
      
   4. For loop (requires TikZ/PGF packages):
      \foreach \n in {01,02,03,04,05,06,07,08}
{
   \input{Chapter\n/main.tex}
}
      
   5. Create relative dir list and fill with 1.tex, 2.tex,....
      \foreach \n in {1,2,...,100}
{
   \IfFileExist{List\n/main.tex}
   {
      \input{List\n/main.tex}
   }
   {}
}
      
   6. Yes, you can use \input in preamble
      \documentclass{article}[10pt]
%%%Preambles in parentdir
...
\input{../Common.tex}
\input{../TikZ.tex}
\input{../Listings.tex}
...
\input{../MyCommands.tex}

4. $\LaTeX$ on the web: MathJax.
5. pdflatex: PDF.
   More:
   1. Not open... Adobe.
   2. Ancestor Postscript.
   3. Vectorial: Scalable!!!!
   4. PDF unrecognized as an image (HTML)...
   5. On the web, convert to SVG: pdf2svg.
   6. Command Line Interface, CLI: Scriptable!!!!
   7. Web printing sucks!! Generate PDF using pdflatex
      Howto:
      1. Generate latex body.
      2. Add preambles: systemic and institucional data.
      3. Save to temporary tex-file (/tmp):
         Unique file name (concurrency).
      4. Execute pdflatex on temporary file:
         cd to temporary dir (/tmp).
      5. Send CGI header then content of PDF file:
         echo "Content-Type: application/pdf\n\n";
echo $this->Read_File("/tmp/tempfile.pdf");
