Hello!

Currently I have these three lines at the start of my invoices:

#+BEGIN_EXAMPLE
#+macro: invoice-no 11
#+date: 2016-06-01
#+title: Invoice #{{{invoice-no}}}
#+END_EXAMPLE

However, sometimes I forget to update the invoice number or date when copying
the old invoice. Since I name my invoices in the format =NN_YYYY-mm-dd.org=
I'm wondering if there's any way I can automatically populate the =invoice-no=
and date macros by parsing the file name? I found the {{{input-file}}}
macro, but I haven't been able to do anything useful with it.

Any help appreciated!

Stig
