=head1 NAME

check_tables.pl - Check the export tables for a product against the components that are in the product.

=head1 SYNOPSIS

check_tables.pl [options] <product>

 Options:

   -help			brief help message

   -man 			full documentation

   -remove			Automatically remove redundant components. See below for details.

   -add             Automatically add missing components. See below for details. 

   -e				Sends a notification email if a component is missing from export table.

=head1 OPTIONS

=over 8

=item B<-help>

Prints a brief help message and exits

=item B<-man>

Prints the manual page and exists

=item B<-remove>

Create a clean version of the export table by removing the redundant entries.

The clean table will be placed in the directory where the tool was run from 

and will have the same name as the export table in perforce. You will need to  

copy it to where you have your Perforce changes mapped in your client. 

=item B<-add>

The same as -remove but will automatically add the missing components. The 

componenets are added with categories D E F and G. 

=item B<-e>

Sends a notification email to SysBuildSupport@Symbian.com if any components

are missing from the export table.

=back

=head1 DESCRIPTION

B<This program> will take a product as an argument and will check the 

export table for that product for consistency. It will report any 

redundant entries in the export table and also any components that are

missing. It will also report any duplicate entries in the export table

itself. If no problems are found it will report that the tables are 

up to date.
