"""
Script for generate 'README.md' pages.

Files:
- 'docs/packages/$PACKAGE/config.json' - package '$PACKAGE' configuration file;
- 'docs/packages/$PACKAGE/README.md' - generated markdown file from the package description json file;
- 'docs/packages/pkglist.json' - list of packages to generate README.md.

Usage:
'python3 ./tools/gen-info.py'

Global variablea and constants:
- 'PACKAGES' - directory with package files;
- 'PKGLIST' - f file with a list of all packages.

Required dependencies:
- 'python-3.10'

Bad things:
- The 'generator.gen_header()' function could have been better.

TODO:
- Add a 'generator.gen_footer()' function.

Sample file 'README.md':

```
