Where a build.ini file is present, commands are read in from
either the [Page] section if there's a department defined or the [Shop]
section if not.
The section can contain one of three commands:
forcecopy=src[,dst] - Always copy regardless.
copy=src[,dst]      - Copy if the destination is older or not existing.
convert=src[,dst]   - Convert the file as a template

Note that if the dst is not defined the destination will be
the runtime folder using the same name.

The src and dst can have pre-defined variables set to commonly used
folders or file names. They are as follows:

%shop%                - The runtime folder
%contents%            - Contents folder inside the runtime folder
%sharedfiles%         - shared_files folder
%lang%                - the current language we're compiling
%media%               - the media folder
%styles%              - the styles folder
%%stylename%          - this style name
%enterfile%           - the name of the enter file e.g. index.html
%pageloc%,%pagefile%  - name of the page file e.g. d1.html for example
%pageloc_nofileext%   - name of the page file without the file extension part
%id%                  - the id of the page

== Without build.ini file ===============

Where no build.ini is present, folders with the following names determine
where files in them are copied to:

copy      - Just copy the file to the Runtime\contents folder.
copylang  - As above but to the Runtime\contents\lang folder.
parse     - Convert the file into the Runtime\contents folder.
parselang - As above but to the Runtime\contents\[lang] folder.
media     - Copy to the Runtime\contents\media folder.
styles    - Copy to the Runtime\contents\styles folder.
