Additional Export options

[srinivas <sp_us@yahoo.com>]

I have a few questions (or possible requests) regarding the
export/publish capability.

1) Is there a way to get the buffer name or file name to be output as
a keyword? I would like to know the source file used to publish the
content. This would result in the filename being part of the
post-amble along with author nfo and creation date.

For example:
#+OPTION: filename:t

2) Is there a way to set a pattern for export file name? For example,
if my org file is called project-notes.org, when publishing notes on a
given date, I would like to have the flexiblity to name the output
file using a pattern such as <filename>-YYYY-MM-DD-<author>-NTS.<ext>,
where YYYY-MM-DD is the export date.

This could be specified in an option. For example:

#+EXPORT_OPTION: output: <filename>-<export-date>-<author>-NTS.<ext>

PS. I have seen a thread where this was briefly discussed using
options as drawer properties - :EXPORT_DATE:. In this scenario the
export date was hard coded. I want to have the flexibility to use the
actual publish instead of hard coding it.
