-    MORE
-============
-
-Version 1.2
-
-The first tool I wanted was a text file pager.  TYPE worked ok, but
-having to hit the space bar at just the right time got on my nerves.
-So I first created PAGE (RIP), then MORE.  As it exists, MORE looks like
-Unix 'more'.  It doesn't support searching with regular expressions
-and silliness like that (that's what uEmacs is for).  But it's a good
-pager.
-
-MORE is invoked with the following format:
-
-   MORE <filespec>...
-
-When the - <filename> (xx%) - prompt appears at the bottom of the screen,
-pressing Q will quit the current file and MORE the next one (if present).
-Hitting ESC at this prompt will stop the program completely (whether more
-files were specified or not).  Pressing SPACE will scroll through another page
-of the file.  RETURN will move forward in the file one line.
-
-MORE supports redirection and pipes.  If the output is redirected away
-from the console, more won't pause for each page.  In this way it can be
-used as a simple text file converter.
-
-The most useful aspect of MORE is it's versatility- it can read regular Apple
-(CR-delimited) TXT and SRC files, Unix text files (LF-delimited), and IBM CRLF
-text files.  All automatically.
-By redirecting output to a file, MORE can convert from Unix or IBM to Apple
-text format.  Neat, eh? (But using MORE is slower than using CONV- see below).
-
-MORE has no option switches- it's too simple.
-
-Change Log:
-
-v1.1 - MORE can now abort either an individual file or all files. Also,
-       changed return from 'advance page' to 'advance line', like the
-       Unix version.
-
-Note:
-
-A filespec is a method of identifying files on a disk.  In the ORCA
-shell, a filespec can contain the = and ? wildcards, in addition to
-plain filenames.  MORE supports multiple filespecs, e.g.
-	more a.c b.c c.c d=.c
-etc.  Any combination of wildcarded and/or vanilla filespecs is allowed.
-This functionality, however, comes at a price.  MORE works only under
-the ORCA shell or a compatible.  At this time, there are no shells truly
-compatible with ORCA.
