 # `etoolbox`: e-TeX tools for LaTeX
 
-## About
-
 The `etoolbox` package is a toolbox of programming facilities geared
 primarily towards LaTeX class and package authors. It provides LaTeX
-frontends to some of the new primitives provided by e-TeX as well as
+frontends to some of the primitives provided by e-TeX as well as
 some generic tools which are not related to e-TeX but match the
-profile of this package. The package is work in progress. Note that
-previous versions of this package were released under the name
-`elatex`.

-## Requirements
-
- - e-TeX
- - `etex.sty` (for LaTeX kernel releases prior to 2015)
-
-## Automatic installation
-
-TeX Live: The `etoolbox` package is included in TeX Live.
-          Use the TeX Live package manager to install it.
-
-MiKTeX:   The `etoolbox` package is included in MiKTeX.
-          Use the MiKTeX package manager to install it.
-
-#Semi-automatic installation
-
-1. Download the file
-
-   http://mirror.ctan.org/install/macros/latex/contrib/etoolbox.tds.zip
-
-2. Unpack the archive in the root directory of the local TeX
-   installation tree, for example
-
-        /usr/local/share/texmf/
-    
-   or
-
-        /usr/share/texmf-local/
-
-   or
-
-        C:\Local TeX Files\
-
-3. Update the file hash tables (also known as the file name
-   database).
-   
-   On teTeX and TeX Live systems, run `texhash` as root (`sudo
-   texhash`). On MiKTeX, run `initexmf --update-fndb` in a command
-   window or use the 'Refresh FNDB' button of the MiKTeX Options
-   window.
-
-## Manual installation
-
-1. Copy the files `etoolbox.sty` and `etoolbox.def` to
-
-        <TEXMFLOCAL>/tex/latex/etoolbox/
-
-   where `<TEXMFLOCAL>` denotes the root of the local TeX installation
-   tree, for example
-
-        /usr/local/share/texmf/
-
-   or
-
-        /usr/share/texmf-local/
-
-   or
-
-        C:\Local TeX Files\
-
-2. The file `etoolbox.pdf` goes to
-
-        <TEXMFLOCAL>/doc/latex/etoolbox/
-
-3. Update the file hash tables (also known as the file name
-   database).

 This command loops over all items in a \prm{listmacro} and executes the auxiliary command \cmd{do} for every item in the list, passing the item as an argument. The list loop itself is expandable. You may use \cmd{listbreak} at the end of the replacement text of \cmd{do} to stop processing and discard the remaining items in the list. Here is a usage example which prints an internal list called \cmd{mylist} as an \env{itemize} environment:
