		+	== '''Confirming Perl is Installed along with Determining Which Version of Perl is Installed''' ==
		+	There are two main methods/switches to display the currently installed version of Perl, with the ONLY difference in the switch is it's case, be it UPPER-CASE or lower-case, using the letter "V", without the quotes, as shown here:
		+	<pre style="color:blue">
		+	jamie@dell16fc42:~$ perl -v
		+
		+	This is perl 5, version 40, subversion 2 (v5.40.2) built for x86_64-linux-thread-multi
		+	(with 15 registered patches, see perl -V for more detail)
		+
		+	Copyright 1987-2025, Larry Wall
		+
		+	Perl may be copied only under the terms of either the Artistic License or the
		+	GNU General Public License, which may be found in the Perl 5 source kit.
		+
		+	Complete documentation for Perl, including FAQ lists, should be found on
		+	this system using "man perl" or "perldoc perl". If you have access to the
		+	Internet, point your browser at https://www.perl.org/, the Perl Home Page.
		+
		+	jamie@dell16fc42:~$
		+	</pre>
		+	<br /><br />
		+
		+	If you change the -v to an UPPER-CASE -V, you get a LOT more information, as shown in this example:
		+	<pre style="color:blue">

 Once the RPM database and it's cache updated, you can then safely install Perl and all of it's additional tools & extra packages, including all of any optional packages available, by also including the "--with-optional" switch, without the quotes, of course, to the full DNF command, as shown in this example, which installs all Perl packages, except for the extra 46,000 extra Perl modules.

 Sometimes, due to the required/desired Perl module is not easily available via the standard command line "MCPAN..." command, or you want to force a specific version or tweak the module's way it works, allowing for total customization, it can be preferable to manually install a Perl module from source code after downloading and compiling.  Here are the basic instructions to do it yourself manually from the command line.  I will use the same Perl module, HTML::Template, referenced in the previous example above.
