usage:
#{Rbnotes::NAME} export [TIMESTAMP [FILENAME]]

Write out a given note into a specified file.  TIMESTAMP must be a
fully qualified one, such "20201108141600", or "20201108141600_012" if
it has a suffix.  FILENAME is optional.  When it omitted, the filename
would be a timestamp string with ".md" as its extension, such
"20201108141600.md"

The file will be created into the current working directory unless an
absolute path is specified as FILENAME.

When no argument was passed, it would try to read a timestamp string
from the standard input.  Then, FILENAME would be regarded as omitted.
