A reader for hledger's journal file format
(<http://hledger.org/MANUAL.html#the-journal-file>). hledger's journal
format is a compatible subset of c++ ledger's
(<http://ledger-cli.org/3.0/doc/ledger3.html#Journal-Format>), so this
reader should handle many ledger files as well. Example:
@
2012\/3\/24 gift
