=head1 SYNOPSIS

Blosxom [pronounced "blossom" or "blogsome"]
is a lightweight (to say the least -- it's &lt;31 lines of code) 
Weblog-in-a-jiffy Perl CGI script for (but in no way limited to) Mac OS X.  
Blosxom simply nabs text documents (written in your text editor of choice)
from a particular directory and displays them (in reverse chronological 
order) as a Weblog.  Simplistic --  but a spot of fun nevertheless.

The idea for Blosxom, while rattling about in my head for some time now,
came to the fore in response to a query on the Forwarding Address: OSX weblog
[http://saladwithsteve.com/osx/2002_02_01_archive.html#9743127] regarding 
the existence of any weblog tool that takes makes use of some of the built-in 
yummy goodness 
of OS X. 

=head1 DESIGN GOALS

=over 4

=item 1. Weblogging should be as natural to the weblogger as the comfort of their favourite text editor, be it BBEdit, vi, emacs, notepad...

=item 2. As much an exercise in silliness as minimalism, Blosxom uses only in-the-box components of OS X and Perl.

=back

=head1 DIRECTIONS

=over 4

=item 1. Make sure you have Apache running.  Under OS X's Control Panels, visit the Sharing panel and start Web Sharing.

=item 2. Plop blosxom into your cgi-bin directory (/Library/WebServer/CGI-Executables on Mac OS X, typically /usr/local/apache/cgi-bin under *nix).

=item 3. Either a) create the default blog directory (on OS X: mkdir /Library/WebServer/Document/blosxom) directory or b) create it somewhere else and alter the $datadir variable in the blosxom script: my $datadir = "/path/to/your/blosxom/data/directory";  Note: the default blosxom data directory may be browsed-to as http://localhost/blosxom and its contents viewed by about anyone; I leave protection of this directory as an exercise for the reader (or a little later documentation).

=item 4. Blog away using your favourite text editor (BBEdit, vi, emacs, TextEdit, et al).  Simply save your blog entries as text documents (be sure to include the .txt extension) into your blog directory and you're off to the races.

=item 5. Point your browser at http://localhost/cgi-bin/blosxom

=item 6. Enjoy!

=back

=head1 STYLE

The format of Blosxom weblog entries is as simple as can be.  The first
line in the .txt file is considered the title, the rest the body.

Blosxom attempts to sandwiche your blog entries between any head.html and 
foot.html it may find in your blog directory, otherwise dropping in rather 
bland bits of required HTML and a largish, uglyish Blosxom header.

Entries themselves are rather plain looking by default, but the HTML includes
stylesheet hooks (blosxomEntry, blosxomDate, blosxomTitle, blosxomBody, 
blosxomTime) which you can style to your heart's content using a home-brewed
CSS stylesheet.
