# By default, rpmbuild will actually install the package's files (although,
# oddly enough, not the package itself) on the current system.  To get
# around that, we can tell it to install everything into a temp directory.
# That also requires that our install section (and by extension, our
# Makefile's "install" target) be flexible enough to install into a
# variable directory.

BuildRoot: /tmp/_PACKAGE_FULL_-_VERSION_

#
# Maya does not list each of its .so files as a separate provided resource,
# so we have to turn off rpmbuild's automatic generation of requirements
# and provide our own.
#
# Unfortunately that also turns off automatic generation of what this
# package provides, so we must specify that ourselves as well.

%description
The _PACKAGE_ plugin allows users of Autodesk's Maya modeling and
animation package to create photorealistic hair on polygonal, NURBS and
subdivision surfaces.  The plugin supports dynamic collisions between the
hairs and other objects.  Tools are providing for styling the hair
interactively.

# Modern rpmbuild implementations have a "build policy" script which
# compiles all python scripts in the tree. We don't want the resulting
# .pyc and .pyo files in our rpm. We can avoid that by explicitly exiting
# the install section and thereby preventing the build policy scripts
# from executing.
