File::Atomism::Protozoa - CAD drawing as an atomised directory
A directory that contains multiple drawing entities each represented by a single file.
A simple file-system directory/folder that contains any number of drawing objects, represented by files; and optionally, any number of further drawings represented by subdirectories.
Note that this is not completely analogous to a traditional monolithic CAD file format, as blocks/symbols associated with a drawing are complete drawings in their own right.
Files titled "DIRTYPE" or beginning with "." or "_" are not considered part of the data and are therefore ignored.
SGI::FAM (File Activation Monitor) is used to grapple the file list.
