Installing xml2rfc and kramdown-rfc2629 on Cygwin

This assumes that python and ruby are already installed...

PIP

Installing xml2rfc requires PIP, so follow first the instructions at https://pip.pypa.io/en/stable/installing/:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py

XML2RFC

As per https://pypi.org/project/xml2rfc/:

pip install xml2rfc

KRAMDOWN and KRAMDOWN-RFC2629

Now things get more interesting, as the instructions at https://kramdown.gettalong.org/installation.html did  not work for me - they install "kramdown", but certainly not in a place where I would find it.

However, "gem" let's you specify where to put the executable, like that:

gem install -n /bin kramdown

And, consequently, for kramdown-rfc2629:

gem install -n /bin kramdown-rfc2629
