Go can cross compile to older ARM architectures (e.g. v5). In order to
do so one needs to use the GOARM parameter as documented in
https://github.com/golang/go/wiki/GoArm
I've added a hint for pre-compiled binaries on windows where to place them for easier use in the shell or in scripts without the hassle for absolute paths.
This commit refactors the documentation according to my proposal in #1273
and the discussion I had with fd0 on IRC.
The bits from the manual that I could not immediately put into the new
structure are contained in manual_rest.rst Anything else is still there,
nothing has been deleted.
I changed the heading markup to follow the convention used in Python’s
Style Guide for documentation, this convention is explained in a comment
at the top of every file.
I also added a paragraph on installing restic on Debian.
