 ## Features
 
 - Auto-indentation.
-- Line continuations are aligned with the previous opening delimiter `(`, `[` or `(/` or with an assignment operator `=` or `=>`. If none of the above is present, a default hanging indent is applied.

 - Consistent amount of whitespace around operators and delimiters.
 - Removal of extraneous whitespace and consecutive blank lines.
 - Change letter case (upper case / lower case conventions) of intrinsics
 - Tested for editor integration.
-- By default, fprettify causes whitespace changes only and thus preserves revision history.
-- fprettify can handle cpp and [fypp](https://github.com/aradi/fypp) preprocessor directives.

 ## Deactivation and manual formatting (experimental feature)
 
-fprettify can be deactivated for selected lines: a single line followed by an inline comment starting with `!&` is not auto-formatted and consecutive lines that are enclosed between two comment lines `!&<` and `!&>` are not auto-formatted. This is useful for cases where manual alignment is preferred over auto-formatting. Furthermore, deactivation is necessary when non-standard Fortran syntax (such as advanced usage of preprocessor directives) prevents proper formatting. As an example, consider the following snippet of fprettify formatted code:

 ## Contributing / Testing
 
-The testing mechanism allows you to easily test fprettify with any Fortran project of your choice. Simply clone or copy your entire project into `fortran_tests/before` and run `python setup.py test`. The directory `fortran_tests/after` contains the test output (reformatted Fortran files). If testing fails, please submit an issue!
