Remove `docwriter' source (now a pip package). 

`docwriter' can now be found at

  https://github.com/freetype/docwriter

The PyPI project is published at

  https://pypi.org/project/docwriter/

Development will continue on the GitHub repository.

* src/tools/docwriter: Remove this folder and its contents from the
repository.

# FreeType Docwriter
Markdown documentation generator for the FreeType library.
## Setup Instructions
1. Clone this repository.
2. Clone the freetype2 repository from [here](http://git.savannah.gnu.org/cgit/freetype/freetype2.git/).
3. Convert the `include/` folder to markdown using the
[freetype-docs](https://github.com/nikramakrishnan/freetype-docs/tree/markdown) repository.
5. Copy files from `include_mark/`.
6. Run:
```bash
python -B docwriter.py --prefix=ft2 --title=FreeType-2.9.1 --output=./docs/reference \
./include_mark/freetype/*.h ./include_mark/freetype/config/*.h ./include_mark/freetype/cache/*.h
```
## Usage Information
```
docwriter [-h] [-t T] -o DIR [-p PRE] [-q | -v] files [files ...]
DocWriter Usage information
positional arguments:
files list of source files to parse, wildcards are allowed
optional arguments:
-h, --help show this help message and exit
-t T, --title T set project title, as in '-t "My Project"'
-o DIR, --output DIR set output directory, as in '-o mydir'
-p PRE, --prefix PRE set documentation prefix, as in '-p ft2'
-q, --quiet run quietly, show only errors
-v, --verbose increase output verbosity
```
## Running Tests
There are two possible test scenarios:
1. Running tests on both py27 and py36 (using tox - requires both python versions installed).
2. Running tests on the currently installed Python version.
They are detailed below.
### Test using Tox
To test on both py27 and py36:
1. Make sure `tox` is installed:
```bash
pip install tox
```
2. Ensure both py27 and py36 are installed.
3. Run tests:
```bash
tox
```
### Test on single python version
To test on current python version using pytest:
1. Make sure `pytest` is installed:
```bash
pip install pytest
```
2. Run tests:
```bash
python -m pytest
```
## License
This library is licensed under the [FreeType License](https://www.freetype.org/license.html).
## History
This library was originally written by David Turner as `docmaker` which collected and presented
documentation in HTML. It has since been modified multiple times, including a major refactor
to allow multiple output formats. The current `docwriter` is the biggest rewrite, with lots of
changes, additions etc. that allow it to be more flexible, readable, maintainable and usable.

## DOC CODE CLASS
##
## The `DocCode' class is used to store source code lines.
##
## `self.lines' contains a set of source code lines that will be dumped as
## HTML in a <PRE> tag.
##
## The object is filled line by line by the parser; it strips the leading
## `margin' space from each input line before storing it in `self.lines'.
