=head1 SYNOPSIS
Backend for the C<blio.pl> command. See L<blio.pl> and/or C<perldoc blio.pl> for details.
more docs pending...
docs provided by gabor, need to be integrated:
=head1 CONFIGURATION
The configuration parameters can be provided either in the configuration file that defauts to blio.ini
or on the command line.
The configuration file can look like this:
name=Test site
source_dir=src/
output_dir=.
template_dir=templates/
The configureation file must exists.
Otherwise you will get a warning like this:
Specified configfile 'blio.ini' does not exist, is empty, or is not readable
If no source_dir provided or there is no src/ directory, you get this exception:
Can't call method "done" on an undefined value at .../Blio.pm line 137.
=over 4
=item name
The name of the site in the title of the pages. Default to Blio
=item source_dir
The directory where the source files are. Each page of the site has a corresponding source file with .txt extension.
Defaults to the C<src/> directory relative to the current working directory where your run the C<build.pl> script.
=item output_dir
Directory where the generated html files should go. Defaults to C<out/> relative to the current working directory.
=item template_dir
The location of the template files. Defaults to C<templates/> relative to the current working directory.
As a fallback, there is a set of templates provided by Blio. They come in the share/templates directory of
the distribution and are installed along the module.
=item site_url
=item site_author
=item converter
=item thumbnail
=back
TODO - there are more fields that need explanation.
=head2 Source directory hierarchy
The source directory defined using the C<source_dir> paramater can havs subdirectories, but each subdirectory needs
a 'parent' page. The name of the parent page is the same as the name of the subdirectory with the additional .txt
extentsion. So if you'd like to have a C<src/project/> subdriectory, you also need to have a page called
C<src/project.txt>.
If there is no index.txt in the src/ directory, Blio will generate a default index.html file.
This is not the case with subdirectories.
=head2 Source files
Each source file has a txt extension. It has several lines of header and a body.
The module that represents each file is L<Blio::Node>.
title: The Project
date: 2013-02-10T00:27:53
language: en
converter: textile
tags: Perl
This is the project page.
The only required entry in the header is the C<title>.
TODO - there are more fields that need explanation.
