##            Notes:  This is the second Attachment Mod I have written. The
##                    earlier mod used the database to store the binary data,
##                    for a huge amount of files, this might start getting hard
##                    to make backups etc. of. (first mod was intended for few
##                    files, not gigabytes of data, but I have come closer and
##                    closer to this, and would like to be able to keep it on
##                    files instead.)
##                    
##                    To be able to get attachments, one need to enable upload
##                    of files in PHP, and set the max_file_size (and some
##                    other variables, so read documentation after installing
##                    the mod)
##                    There's now no longer any need of having large buffers
##                    for the database, so these can be returned to the values
##                    one had before installing the first mod (if you have that
##                    installed, but I guess you should do that after the files
##                    has been converted to disk files)
##                    
##                    There's also no need for editing php files to set options,
##                    these are set in the Administration interface, located in
##                    the Plugins menu. These are cached and should therefore be
##                    at least just as quick (perhaps quicker as they're
##                    combined with the forum config), so it's easier to
##                    administrate the mod now, adding icons, and such.
##                    
##                    Another great new thing done is that you only have to
##                    backup each file once, as there will never be two files
##                    with the same name in a directory. So one only need to
##                    download the new files from the subfolders, old deleted
##                    files will be emptied (0 bytes), but still be in the
##                    folders to keep new attachments to get the same name. As
##                    if they would, one would need to download all files during
##                    backup procedure.
##                    
##                    And as a further upgrade, posts are no longer limited to
##                    one attachment per post. I still have a limit of one file
##                    per opportunity (i.e. one on post creation, rest on edit),
##                    but the admin set the limit of max files per post, a per 
##                    group and per forum basis.
##                    
##                    I strongly suggest you read the whole documentation
##                    before start using the mod, the documentation is in the
##                    Administration interface. Or at the very least the first
##                    chapter!

##                    **** PREPARATIONS NEEDED TO BE DONE FIRST! ****
##
##                    1. Backup!
##                    2. Create a directory where you want the attachments to
##                       be stored. (Suggestion is somewhere the browser does
##                       NOT reach, if not bruteforcing to find files is
##                       possible)
##                    3. Make sure php is allowed to create files and
##                       directories in the above directory.
