Character mappings between filename formats
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The two files in this directory ("Acorn" and "Psion") allow you to define
which characters are converted into which characters when converting
filenames.

The Acorn file contains the translations used when converting Psion filenames
into Acorn filenames. It consists of up to 256 characters, each on a separate
line, followed by a single tab (CHR$ 9) character, followed by another
character.

Each of the first characters in Psion filenames will be substituted for the
second character (ie. after the tab) when converting to Acorn filenames.

For example, the following line will convert all fullstops in Psion filenames
into forward slash (/) characters in Acorn filenames.

.	/

The Psion "Psion" follows exactly the same format but contains the mappings
used when converting Acorn filenames back into Psion filenames.


Filetype conversions
~~~~~~~~~~~~~~~~~~~~
At present I haven't worked out how the Psion 5 stores it's filetypes when
files aren't suffixed by the usual .xxx type extension. However, i have now
supplied a mapping file to convert Psion file extensions into Acorn filetypes.
This is called 'filetypes' and contains three columns;
Firstly, the Psion file extension, followed by a tab and then lastly the
relevant Acorn filetype to translate to.
