To insert some environment values during the evaluation process, the document factory provides several functions that can be used in entities or templates:

&base(file name);

removes path information and the extension from the file name, e.g.:

&base(/home/bscw/www/faq.bht); -> faq

&rel(path);

generates a relative pathname out of an absolute one, relative to the document that will be generated, e.g.:

If one uses &rel(/Images); in a template, that generates the document /faq/index.htm, it is evaluated to ../Images. If one use it in a template, that generates the document /faq/question/install.htm, it is evaluated to ../../Images.

&size(file name, [B|K|M|G]);

inserts the size of a file specified by 'file name' in Bytes, Kilobytes, Megabytes or Gigabytes, respectively, depending on the value of the second parameter, e.g.:

&size(/Download/bscw34.exe, M); -> 8.43

&date(format);

inserts the local time. The following directives can be embedded in the format string. They are shown without the optional field width and precision specification:

%a	Locale's abbreviated weekday name.
%A	Locale's full weekday name.
