Browse Source 
Supported modes are:
- strip (don't export)
- raw (compatibility)
- octal (export as \ooo)

Note that gmdb2 dialog where updated, but not the code. Many fixes to do
there first :/

mdb-export - Export data in an MDB database table to CSV format.
SYNOPSIS
mdb-export [-H] [-d delimiter] [-R row_delim] [[-Q] | [-q quote [-X escape]]] [-I backend] [-D format] [-N namespace] database table
mdb-export [-H] [-d delimiter] [-R row_delim] [[-Q] | [-q quote [-X escape]]] [-I backend] [-D format] [-N namespace] [-b strip|raw|octal] database table
DESCRIPTION
mdb-export is a utility program distributed with MDB Tools.
@ -10,15 +10,16 @@ DESCRIPTION
It produces a CSV (comma separated value) output for the given table. Such output is suitable for importation into databases or spreadsheets.
OPTIONS
-H Supress header row
-Q Don't wrap text-like fields (text, memo, date) in quotes. If not specified text fiels will be surrounded by " (double quote) characters.
-d Specify an alternative column delimiter If no delimiter is specified, table names will be delimited by a , (comma) character.
-R Specify a row delimiter
-I backend INSERT statements (instead of CSV). You must specify which SQL backend dialect to use. Allowed values are: access, sybase, oracle, postgres and mysql.
-D Set the date format (see strftime(3) for details)
-q Use to wrap text-like fields. Default is ".
-X Use to escape quoted characters within a field. Default is doubling.
-N namespace Prefix identifiers with namespace.
