I'd advise against using any file as the right file for documentation
purposes. There are just too many edge cases.
Something I think would be amusing rather than instructive would be to
put all of the example tx in the docs into one file. I doubt it would
be useful to anyone other than an historian of finance programs but it
would be fun to see what we ended up with. If someone is thinking of
presenting a paper at a conference try it, mention me if you are feeling

gnc is a transaction stream application. each time you open a file it
starts from 0 and does addition and subtraction. no more no less.
on top of that we have pretty stuff, convenient ways of adding new
transactions to the stream, convenient ways of reporting the results of
nevertheless, it is still just a program interpreting a stream of
gnc is a convenience. I don't see why I should have to give live data
to people I don't know in person ... and I don't even have super secret
stuff like tax havens or a Donald Trump blow job account or a religious
I just feel uncomfortable showing ordinary tx to people I don't know, it
is that simple to me.
Q: Why does someone need to see *my* (or your) tx to fix a problem?
A: they don't
So, we are stuck.
