On the Website, there is a set of interconnected pages related
to compiling from source, the Debian package and our DEB depot.
Although these pages have always been superficially kept up-to-date,
the overall presentation feels dated and generally not well organized.
During the last weeks, I have almost entirely rewritten all those pages,
added information about the (now reworked) DEB package, explained the
alternate ways to build from a Debian source package (notably the
`mk-build-deps` for handling the build dependencies, which effectively
the only method which always worked during the last years, since our
DEB package was totally outdated)
Furthermore, I have tested most of the build steps with the current
source trees, repositories and package definition, and finally I
have also updated and polished the front-page of our DEB-Depot
(-> see commit on the depot-Branch)
Wheew ... quite some work done!
* Simplify some constructs from the Python-3 migration
* update copyright, since I did maintain the SCons build continuosly
* remove unused method from Buildhelper
Furthermore, the documentation page for our build system
https://lumiera.org/documentation/technical/build/SCons.html
has been reworked, to add a synopsis, some further background
information about the internal structure of SCons and about
the specific conventions and definitions used for Lumiera
Mostly, std::regexp can be used as a drop-in replacement.
Note: unfortunately ECMA regexps do not support lookbehind assertions.
This lookbehind is necesary here because we want to allow parsing values
from strings with additional content, which means we need explicitly to
exclude mismatches due to invalid syntax.
We can work around that issue like "either line start, or *not* one of these characters.
Alternatively we could consider to make the match more rigid,
i.e we would require the string to conain *only* the timecode spec to be parsed.
