/**	@file	dk3paper.h

The module reads configuration files named "dk3paper.conf" and creates
a collection of paper sizes.

After opening a paper size collection using dk3paper_open_app() one
can search for a paper size by name using the dk3paper_find()
function. This function returns a dk3_paper_size_t structure.

To inspect all known named paper sizes, use code like this:
@code
  dk3_named_paper_size_t	*nsz;

  dk3paper_reset(psc);
  while((nsz = dk3paper_next(psc)) != NULL) {
    /* Do something with the named paper size. */
  }
@endcode

The dk3paper.conf files contain named paper sizes, one per line.
Each line consists of the paper size name, the '=' character
and either 2 or 6 values. The values specify dimenstions in PS points:

* paper width,
* paper height,
* left border (inner border for duplex printing in book mode),
* right border (outer border for duplex printing in book mode),
* top border (inner border for duplex printing in calendar mode), and
* bottom border (outer border for duplex printing in calendar mode).

Example dk3paper.conf entries:
@code
A4		=	595	842
a4		=	595	842	56	28	14	14
@endcode
