Since C++17 we can use the std::filesystem instead (and we ''do use it'' indeed)
- relocate the `/lib/file.hpp` header
- adapt the self-discovery of the executable to using std::filesystem
Furthermore, some recherche regarding XVideo and Video Output
- most notably the NOBUG logging flags have been renamed now
- but for the configuration, I'll stick to "GUI" for now,
since "Stage" would be bewildering for an occasional user
- in a similar vein, most documentation continues to refer to the GUI
The important page on contacting Lumiera was buried below
somewhere in Contributing to Lumiera. This information must
be provided top-level and easily accessible. So I've added it,
maybe not terribly suitably, to the tutorials page. However its
position there is saved and justified by placing it under the
tutorial on contributing to Lumiera.
Maybe someone has a better idea.
this is a bit trickty, since we need to install gcc-4.9 from a PPA.
Mint only provides the libstdc++ 4.8, which is known to break when
compiling in C++14 mode
This means we have rather tight compiler requirements now.
Beyond that, we expect no serious impact; the most notable
C++14 feature we're likely to use soon is type inference
on lambda arguments.
Some obvious typos were corrected. Other material improved.
The section on Git was considerably improved.
An entirely new section on Git was added, but which contains some previous
material on git.
The reason for adding a new section on Git was I though it better to have one
single place where someone new to Git and Lumiera could read a simple
recipe-type explanation on how to retrieve source code, make changes and then
push the changes. All information necessary including Git, links, etc should be
on this page, no following liknks. In fact there is no real _new_ information
here that isn't to be found somewhere else. The point being that _all_
information necessary to ge someone up and going is located on one page.
For this reason, I added information on the mailing list and IRC; again, all
essential information in how to contribute to Lumiera, the title ang goal of
this page.
There might be stuff missing here, so please add, but do not make this page too
long. That tends to scare people, in fact, someone might just like to shorten my
contributions here, that would be good!
