+Selecting budget goals
+
+The budget report evaluates periodic transaction rules to generate
+special "goal transactions", which generate the goal amounts for each
+account in each report subperiod. When troubleshooting, you can use the
+print command to show these as forecasted transactions:
+
+$ hledger print --forecast=BUDGETREPORTPERIOD tag:generated
+
+By default, the budget report uses all available periodic transaction
+rules to generate goals. This includes rules with a different report
+interval from your report. Eg if you have daily, weekly and monthly
+periodic rules, all of these will contribute to the goals in a monthly
+budget report.
+
+You can select a subset of periodic rules by providing an argument to
+the --budget flag. --budget=DESCPAT will match all periodic rules whose
+description contains DESCPAT, a case-insensitive substring (not a
+regular expression or query). This means you can give your periodic
+rules descriptions (remember that two spaces are needed), and then
+select from multiple budgets defined in your journal.
