+; HISTORY
+; 9/88, created
+; modified 1/19/89, allow books with editor but no author;
+;                   added %O ordering field;
+;                   appended illegal multiple fields, instead of 
+;                     discarding;
+;                   added rule, a tech report whose %R number
+;                     contains "ISBN" is really a book
+;                   added rule, anything with an editor is a book
+;                     or a proceedings
+;                   added 'manual type, for items with institution
+;                     but no author or editor
+;                   fixed bug so trailing blanks are trimmed
+;                   added 'proceedings type
+;                   used "organization" field for proceedings
+; modified 2/16/89, updated help messages
+; modified 2/23/89, include capitalize stop words in r2b stop words,
+;                   fixed problems with contractions (e.g. it's),
+;                   caught multiple stop words in a row
+; modified 3/1/89,  fixed capitialize-title for first words all caps
+; modified 3/15/89, allow use of " to delimit fields
+; modified 4/18/89, properly "quote" special characters on output

+
+A refer-style database is of the form:
+
+%A Joe Blow
+%T Great Thoughts I've Thought
+%D 1977
+etc.
+
+This utility converts these kind of databases to bibtex form, for
+users of TeX and LaTex.  Instructions:
+1.  Visit the file containing the refer-style database.
+2.  The command
+	M-x r2b-convert-buffer
+    converts the entire buffer, appending it's output by default in a
+    buffer named *Out*, and logging progress and errors in a buffer
+    named *Log*.  The original file is never modified.
+	Note that results are appended to *Out*, so if that buffer
+	buffer already exists and contains material you don't want to
+ 	save, you should kill it first.
+3.  Switch to the buffer *Out* and save it as a named file.
+4.  To convert a single refer-style entry, simply position the cursor
+    at the entry and enter
+	M-x r2b-convert-record
+    Again output is appended to *Out* and errors are logged in *Log*.
+
+This utility is very robust and pretty smart about determining the
+type of the entry.  It includes facilities for expanding refer macros
+to text, or substituting bibtex macros.  Do M-x describe-variable on
+     r2b-journal-abbrevs
+     r2b-booktitle-abbrevs
+     r2b-proceedings-list
+for information on these features.

+If you don't want to see this help message when you load this utility,
