+.It Nm budget Oo Ar report-query Oc
+A special balance report which includes three extra columns: the amount
+budgeted during the reporting period, how spending differed from the budget,
+and the percentage of budget spent (exceeds 100% if you go over budget).
+Note that budgeting requires one or more

+to be defined in your data file(s).  See the manual for more information.
+.It Nm cleared Oo Ar report-query Oc
+A special balance report which adds two extra columns: the cleared balance for
+each account, and the date of the most recent cleared posting in that account.
+For this accounting to be meaningful, the cleared flag must be set on at least
+one posting.  See the manual for more information.
+.It Nm csv Oo Ar report-query Oc
+Report of postings matching the
+.Ar report-query
+in CSV format (comma-separated values).  Useful for exporting data to a
+spreadsheet for further analysis or charting.
+.It Nm draft Oo Ar draft-template Oc
+Generate and display a new, properly formatted Ledger transaction by comparing
+the

+to the transactions in your data file(s).  For more information on draft

-.It Nm generate
-.It Nm prices Oo Ar query Oc

+.It Nm equity Oo Ar report-query Oc
+Prints a series of transactions that balance current totals for
+accounts matching the
+.Ar report-query
+in a special account called
+.Li Equity:Opening Balances .
+The purpose of this report is to close the books for a prior year, while using
+these equity transactions to carry forward those balances.
+.It Nm prices Oo Ar report-query Oc
+Reports prices for all commodities in postings matching the
+.Ar report-query .
+The prices are reported with the granularity of a single day.
+.It Nm pricesdb Oo Ar report-query Oc
+Reports prices for all commodities in postings matching the
+.Ar report-query .
+Prices are reported down to the second, using the same format as the
+.Li ~/.pricedb
+file.
+.It Nm print Oo Ar report-query Oc
+Prints out the full transactions of any matching postings using the same
+format as they would appear in a data file.  This can be used to extract
+subsets from a Ledger file to transfer to other files.

+.It Nm register Oo Ar report-query Oc
+List all postings matching the

+.It Fl \-current Pq Fl c

+.It Fl \-exchange Ar commodity Pq Fl X
+Render all values in the given
+.Ar commodity ,
+if a price conversion rate can be determined.  Rates are always displayed
+relative to the date of the posting they are calculated for.  This means a

+to use the
+.Nm balance
+report.
+.It Fl \-gain Pq Fl G
+Show any gains (or losses) in commodity values over time.

+Only show the top
+.Ar number
+postings.
+.It Fl \-invert
+Invert the value of amounts shown.
+.It Fl \-market Pq Fl V
