FAQ/FAQ.mkd, FAQ/Makefile: this version of the FAQ is now out of date
    and probably should be deleted.

InternetArchive/repair_item: script to upload missing shows after tie
    out errors during the normal upload; still under development.

InternetArchive/update_state: script to update show state in the
    'reservations' table in the database. Uses the CMS interface.

Link_Checker/scan_links: under development. Not currently usable.

Miscellaneous/fix_tags: audio metadata manipulation script. Recently
    added to this repo for convenience. Updates for 'experimental::try',
    the official Perl try/catch.

PostgreSQL_Database/add_hosts_to_show, PostgreSQL_Database/hpr_schema_2.pgsql,
    PostgreSQL_Database/nuke_n_pave.sh: an old experimental Pg database
    to take over from the previous MySQL version (from before 2023).
    Kept for reference; never implemented.

#=== FUNCTION ================================================================
# NAME: find_external_links
# PURPOSE: Parses the HTML in a string for links so that attached assets
# on the HPR site can also be parsed and to collect external
# links for testing.
# PARAMETERS: $episode episode number we're dealing with
# $html string containing HTML
# $rlinks hashref to receive the links found
# RETURNS: Number of links found
# DESCRIPTION: Given HTML from the main notes or a subsidiary file the
# function parses this looking for links in 'a' or 'img' tags.
# Links are standardised, making them absolute if relative and
# removing any 'fragment'. The links need to be to HTML files on
# the HPR website to be of use in recursing to subsidiary
# levels. Otherwise they need to be external links that we will
# test.
# Having found a local link the filename part is extracted. If
# it follows the format 'hpr9999' then it's checked to see if
# it's for the current show. If not it's ignored. If the
# filename ends with a '/' then it's assumed it's shorthand for
# 'index.html' so this name is appended. If the local filename
# ends with '.html' then we need to parse it in turn, so we get
# the contents of the link and recurse to parse it.
# Then, if external, the link and filename are stashed in the
# hash referenced by $rlinks. We return the number of external
# links found in the pass through the HTML.
# THROWS: No exceptions
# COMMENTS: Based on 'find_links' in 'upload_manager'.

<application name> - <One line description of application's purpose>
=head1 VERSION
The initial template usually just has:
This documentation refers to <application name> version 0.0.2
=head1 USAGE
# Brief working invocation example(s) here showing the most common usage(s)
# This section will be as far as many users ever read
# so make it as educational and exemplary as possible.
=head1 REQUIRED ARGUMENTS
A complete list of every argument that must appear on the command line.
when the application is invoked, explaining what each of them does, any
restrictions on where each one may appear (i.e. flags that must appear
before or after filenames), and how the various arguments and options
may interact (e.g. mutual exclusions, required combinations, etc.)
If all of the application's arguments are optional this section
may be omitted entirely.
=head1 OPTIONS
A complete list of every available option with which the application
can be invoked, explaining what each does, and listing any restrictions,
or interactions.
If the application has no options this section may be omitted entirely.
=head1 DESCRIPTION
A full description of the application and its features.
May include numerous subsections (i.e. =head2, =head3, etc.)
=head1 DIAGNOSTICS
A list of every error and warning message that the application can generate
(even the ones that will "never happen"), with a full explanation of each
problem, one or more likely causes, and any suggested remedies. If the
application generates exit status codes (e.g. under Unix) then list the exit
status associated with each error.
=head1 CONFIGURATION AND ENVIRONMENT

including the names and locations of any configuration files, and the
meaning of any environment variables or properties that can be set. These
descriptions must also include details of any configuration language used

restrictions on versions, and an indication whether these required modules are
part of the standard Perl distribution, part of the module's distribution,
or must be installed separately.

A list of any modules that this module cannot be used in conjunction with.
This may be due to name conflicts in the interface, or competition for
system or program resources, or due to internal limitations of Perl
(for example, many modules that use source code filters are mutually
incompatible).
=head1 BUGS AND LIMITATIONS
A list of known problems with the module, together with some indication
whether they are likely to be fixed in an upcoming release.
Also a list of restrictions on the features the module does provide:
data types that cannot be handled, performance issues and the circumstances
in which they may arise, practical limitations on the size of data sets,
special cases that are not (yet) handled, etc.
