Ledger essentially follows five steps in\ +reporting data to the user:\ +\ +@enumerate\ +@item Parse journal file into an internal representation\ +@item Perform any implied math within the journal file\ +@item ``Face'' this internal representation as a virtual document\ +@item Apply a series of transforms to the virtual document\ +@item Display the virtual document using a formatting command\ +@end enumerate\ +\ +The calculations in step two are specified by the user, such as when a\ +posting's value might contain mathematical operators. The\ +calculations in step four are implied in the transformations, for\ +example when the @option\{--average\} option is used.\ +\ +At the core, however, Ledger is basically a sophisticated calculator\ +with special knowledge about commoditized values. It knows what you\ +mean if you add ten dollars to twenty euros, and later ask for the\ +balance of that particular account. So it follows that first we must\ +discuss how Ledger deals with math, and from there move on to describing\ +how the steps above are achieved.}
