What's the D way of application version numbers?

[Russel Winder]

With C++ and Python, it is idiomatic to put the application version
number in a separate file that can then be processed by the build
system. For C++ a config file is constructed defining a macro that is
then used in the rest of the course. For Python the file is read at
runtime to define a variable. The build system itself uses the version
number for creating deb, RPM, egg, wheel, etc. packages.

D has no macro processing so C++ idioms are not useful. D does create a
standalone executable and so the Python approach of reading the file at
initialization time seems inappropriate.

Is there a known D idiom for this?

Thanks.
