# [Fedora-specific] Remove scenario variables: values are fixed on Fedora.
#
#   One could also not remove these variables and just restrict their values,
#   but then these variables would still be visible in, for example,
#   GNAT Studio and may confuse the user.

%description

This package contains various libraries, such as a wide range of containers, as
well as lemmas to use directly in user code.

Please note that SPARKlib is used differently compared to how Ada libraries are
used. In short: if you want to use SPARKlib in your project, then, depending on
your runtime, copy either GPRbuild template "sparklib.gpr.templ" or
"sparklib_light.gpr.templ" from "%{_datadir}/%{name}/templates" to your own
project directory, remove the "templ" extension, edit the file (add an object
directory, exclude source files that are not needed in your project) and
reference the it in your own project file.

See also section 5.11.1 SPARK Library in the SPARK user's manual (part
of package spark2014-doc) for details.
