# hledger-dc JOURNALFILE CMD [ARGS]

|
# instead of/in addition to amount signs.

# If a posting begins with Dr<WHITESPACE>, remove that.
|
|
# If it begins with Cr<WHITESPACE> and contains no number, remove that.
|
|
# If it begins with Cr<WHITESPACE>, remove that and add a minus sign before the next number, and if that leaves a double minus, cancel those out.
