-You can use **astyle** to format the code. The required config flies are: `docs/astyle_c` and `docs/astyle_h`.
-To format the source files: 
- `$ find . -type f -name "*.c" | xargs astyle --options=docs/astyle_c`
- 
-To format the header files:
- `$ find . -type f -name "*.h" | xargs astyle --options=docs/astyle_h`
- 
-Append `-n` to the end to skip creation of backup file OR use `$ find . -type f -name "*.bak"  -delete` (for source file's backups) and `find . -type f -name "*.orig" -delete` (for header file's backups)
+You can use **astyle** to format the code. Run `code-formatter.sh` from the `scrips` folder.
