Why so many print statements out there? I'd rather do like this:
sub Usage() {
my $err = shift and select STDERR;
print <<EOF;
------------------------------------------
-- Usage for the database backup script --
------------------------------------------
--host
Specify the host IP
--engine
Specify the database engine. This could be postgres or mysql.
--password
Give the password needed to connect with the database server
--user
Specify user to connect to the database server.
The user must have permissions to connect to the database(s)
--port
If another port than the standard must be used to connect you co
+uld
specify this with the --port option
EOF
exit $err;
}
It is more readable to my eyes.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
