 =========
 
 This is mysql2sql, a mysql to sql converter. It is primary intended to
-convert mysqldump (especially with extended INSERT syntax) to standard
-SQL to load at least to PostgreSQL or SQLite.

-The program is in its initial phase and currently cannot do much. It only
-removes /\*! directives \*/ and passes everything else unmodified.
+The program removes /\*! directives \*/, unquotes names quoted with
+backticks, quote non-lowercase names with double quotes, unescapes strings
+and escapes them to a different quoting style, and splits extended INSERTs
+into a series of plain INSERTs separated by newlines. Everything else is
