Expand explanation of tool

[rsromanowski]

Found a helpful comment on HN thread to help describe the tool. Consider adding to Readme:

argparse equivalent for Bash.

You provide a YAML file listing commands, subcommands, arguments, and flags, and it automatically generates a Bash script that can parse and validate them, provide help messages, and run your code for each command.

It also lets you keep the actual code for each command and subcommand in separate files, which are merged together into one distributable Bash script at generation time.

It's basically a templating system to auto-generate argument parsing so you don't have to solve that again or deal with things like optparse.

Yes, I saw this discussion. Thanks for opening this issue.

I must say, it felt like most people there did not bother reading anything on the bashly homepage.

Do you still feel like these sentences describe it better than the welcome page and the getting started page?

(and by the way, some of the claims in the three statements are incorrect, but I can fix that).

I have updated the README in the spirit of the statements you have provided + the Features list from the homepage.

Is that better?

I am closing, feel free to comment if you still feel it needs work.
