- Syntax: help

- Description:
-
- help : Prints a list of available help files. Help first
- prints out the help files in the default help file
- directory. Next, the directories identified in the
- environment variable RLAB_SEARCH_PATH are searched for
- files ending in `.r' -- rfiles. A list of each
- directory's rfiles is printed on the standard output.
-
- help name : Prints out the help file identified by name. If
- name matches a file in the default help directory, that
- file is paged to the standard output. If no match is
- found, the directories identified in the environment
- variable RLAB_SEARCH_PATH are searched for matches. The
- first match is paged to the standard output. The rfile
- extension (`.r') is not considered when checking for
- matches.
-
- If the user's environment does not contain RLAB_SEARCH_PATH,
- then the default search-path is used. The default is set at
- compile time. Normally the default is ".", the current working
- directory.
-
- Help is a command, not an expression or statement. Therefore,
- it must be issued on a line by itself, and cannot occur in the
- midst of another statement or expression. See `help COMMAND'.
-
- Help files that are spelled with uppercase letters contain
- general information. For instance, `help MATRIX' provides
- general information about matrix usage.
