+# This script works by using SnoopCompile to log compilations that take place
+# while running the examples on the GR backend. So SnoopCompile must be
+# installed, and StatsPlots, RDatasets, and FileIO are also required for
+# certain examples.

+
+# Anonymous functions may appear in precompile statements as functions with
+# hashes in their name. Those of the form "#something##kw" have to do with
+# compiling functions with keyword arguments, and are named reproducibly, so
+# can be kept. Others generally will not work. Currently, SnoopCompile includes
+# some anonymous functions that not reproducible, but SnoopCompile PR #30
+# (which looks about to be merged) will ensure that anonymous functions are
+# actually defined before attempting to precompile them. Alternatively, we can
+# keep only the keyword argument related anonymous functions by changing the
+# regex that SnoopCompile uses to detect anonymous functions to
+# r"#{1,2}[^\"#]+#{1,2}\d+" (see anonrex in SnoopCompile.jl). To exclude all
