%description
GLM is a C++ library for doing mathematics operations
required in many OpenGL based applications. Its interface
has been designed to resemble the built-in matrix and vector
types of the OpenGL shading language.

%{name}-devel is only required for building software that uses
the GLM library. Because GLM currently is a header-only library,
there is no matching run time package.

# Some glm releases, like version 0.9.3.1, place contents of
# the source archive directly into the archive root. Others,
# like glm 0.9.3.2, place them into a single subdirectory.
# The former case is inconvenient, but it can be be
# compensated for with the -c option of the setup macro.
#
# When updating this package, take care to check if -c is
# needed for the particular version.
