Empty line in requirements.txt

[windelbouwman]

Hi!

Just wanted to let you know, this is very cool.

I ran into a series of issues when given this tool a go:

• an empty line in a requirements.txt file assumes you want to install '', which I did not. Maybe a good idea to filter out empty lines?
• When using a distrbution url, you have to include the trailing slash. Since I copied the distribution url straight from my sources.list file, I did not include the trailing slash. Maybe change this so that a trailing slash is not required?

Another idea I had was to specify all the command-line parameters into a single yaml file, something like this:

distribution: ubuntu
distribution-url:  http://ports.ubuntu.com/ubuntu-ports
arch: arm64
packages:
- systemd
- opencv

It would also be helpful to list an example invocation of the cross compiler with the sysroot flag.

One last question:
How is this approach different / better than using debootstrap?
