+## TAX REPORTS
+#
+# Tested with hledger 1.5.99, osx high sierra.
+# "make" generates the following reports in three formats, 
+# "make preview" prints them on stdout.
+# (You'll need to customise these for your needs.)
+#
+# business revenue
+# business expenses
+# possibly business/tax-related expenses:
+#  trips, travel
+#  trips, other
+#  personal development
+#  health
+#  tax
+# non-business/non-tax-related:
+#  other income
+#  other expenses
