-## Aims
-
-This project aims to provide a command-line tool for formatting
-LaTeX source code files with the following properties:
-
-- Handling of the common LaTeX file types `.tex`, `.bib`, `.cls`, and `.sty`
-- Very good run-time performance
-- No configuration necessary
-
-It does *not* currently aim to provide the following:
-
-- Semantic parsing of LaTeX code
-- Linting or correction of syntax errors
-- Customization via configuration files
-- Compliance with existing formatting guidelines
-- Editor integration
-- Spell checking
-
 ## Performance
 
-Run `perf.sh` to format all test cases in the `tests/` directory.
-For larger files, tex-fmt is hundreds of times faster than latexindent.

 ** Look for problem cases in other latex documents
 * Features
-** TODO Environments should start and end on new lines
-*** New line before begin/end with regex replace
-*** Care with comments
