+Alembic is an open computer graphics interchange framework. Alembic
+distills complex, animated scenes into a non-procedural, application-
+independent set of baked geometric results. This 'distillation' of
+scenes into baked geometry is exactly analogous to the distillation
+of lighting and rendering scenes into rendered image data.
+
+Alembic is focused on efficiently storing the computed results of
+complex procedural geometric constructions. It is very specifically not
+concerned with storing the complex dependency graph of procedural tools
+used to create the computed results.
+
+HDF5 is an optional dependency autodetected with the support enabled by
+default if found in your system. You can disable it passing to the
+script an environment variable as following:
+   HDF5=no ./alembic-framework.Slackbuild
+
+alembic-framework is an optional dependency for Blender autodetected.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
