Can I assemble lots of different writings to a new future document (book)?
Suppose I write various types of scientific material,
- LaTeX document,
- blog posts (HTML),
- web pages (HTML),
- Sphinx documents,
- IPython notebooks,
- wikis,
- Markdown files, ...
and later want to collect the pieces into a larger document, maybe
some book - is that at all feasible?
Probably not, but I have a solution
