As TopAnswers now supports tag descriptions (see https://topanswers.xyz/meta?q=538), it is time to collect them.
I propose to add a separate answer for each tag, so that comments can link to the answer they are about and we can keep track of the history easily.
List of tags without description:
for questions connected to the creation of tables, e.g. using `tablular`, `tabularx`, `longtable` etc.
for questions related to the usage of fonts in TeX and friends
is a pgf-based package for generating graphics with LaTeX.
a documentclass for creating presentations, posters etc.
allows to include images in many common formats into a LaTeX document. It is an extended version of the `graphics` package providing a key=value interface to control the appearance of the graphics.

is "the cool TeX automation tool". With it you can give instructions in your TeX file on how it should be compiled.
