99 | =head1 DESCRIPTION |
100 | |
101 | This script is part of the SQL Fairy project. It will try to convert |
102 | any source file for which it has a grammar into any format for which |
103 | it has a producer. |
104 | |
105 | If using "show-warnings," be sure to redirect STDERR to a separate file. |
106 | In bash, you could do this: |
107 | |
108 | $ sql_translator.pl -f MySQL -t PostgreSQL --show-warnings \ |
109 | file.sql 1>out 2>err |
110 | |
111 | You can specify a parser or producer located in any module that Perl |
112 | knows about, allowing you to easily substitute your own. |
