-description:
-
-    This package is designed to support all the L-systems used in the
-    'Algorithmic Beauty of Plants' by Prusinkiewcz and Lindenmayer. Stochastic,
-    context-sensitive, branching, parametric L-systems are supported. For more

+# A snapshot resolver dictates the compiler version and the set of packages
+# to be used for project dependencies. For example:
+#
+# resolver: lts-3.5
+# resolver: nightly-2015-09-21
+# resolver: ghc-7.10.2
+# resolver: ghcjs-0.1.0_ghc-7.10.2

+# The location of a snapshot can be provided as a file or url. Stack assumes
+# a snapshot provided as a file might change, whereas a url resource does not.
+#
+# resolver: ./custom-snapshot.yaml
+# resolver: https://example.com/snapshots/2018-01-01.yaml
+resolver: lts-12.9

+# User packages to be built.
+# Various formats can be used as shown in the example below.
