5.3.4. - Adding Site-Dependent Help Files
If a file named .local in the spec_help subdirectory of the auxiliary file directory exists and contains a list of file names, those names will be added to the topics contained in the help help file when spec is installed.
When spec starts up, the help file news, which is provided by CSS, and the file local, if it exists, will be displayed. The help file format is described 2.4.1.2 in the Reference Manual.
