+All files and subdirectories of /usr/share/dict are recommended for
+rdisting except web2 and web2a (because of their size), and some of
+the files hlist* depending on needs of your machine (details below).
+Descriptions of most of these files are given under FILES below.
+
+The new subdirectory "special" contains lists of words in specialized
+fields, which may be hashed in with the regular lists on machines having
+many users working in these fields. As of this writing, there are two
+such specialized wordlists.
+
+It is advised that system managers also create a directory
+/usr/local/dict. This can be used to maintain files of particular
+interest to users of each machine (e.g., surnames of members of the
+department on a departmental machine).
+
+The hashed wordlists hlista and hlistb in this distribution include
+the words in the file special/4bsd, comprising current 4bsd
+commands, system calls, etc. (from "abs" to "zcat"). Machines
+whose primary users are programmers should take these files by
+rdist. For machines with other user populations, a file "hlist" is
+provided which only contains the contents of /usr/dict/words. Managers
+of such machines should rdist this file, and use "spellin" to produce
+files hlist{a,b} which contain the words from
+/usr/share/dict/{american,british} respectively, plus any other files
+appropriate to the needs of the majority of their users. (Some basic
+unix commands and terms that general users are likely to encounter,
+e.g. troff, emacs, tty, have been included in /usr/share/dict/words.
+More may be added as suggestions are received.) Here, for instance is a
+script that might be used to create the hashlists on a particular
+machine, so as to include the words in /usr/share/dict/special/math, as well
+as two local lists which we will assume are called
+/usr/local/dict/surnames and /usr/local/dict/acronyms.
+
+ #
+ cd /usr/share/dict
+ cat american special/math /usr/local/dict/{surnames,acronyms} | \
+ spellin hlist > hlista
+ cat british special/math /usr/local/dict/{surnames,acronyms} | \
+ spellin hlist > hlistb
+
+ Hashlists can also be created from scratch using
+/usr/src/usr.bin/spell/Makefile. This is now written so that if "make"
+is run with no options it will produce the hashed files as presently
+distributed, but so that the extra wordlists used can be controlled with
+variables LOCAL and SPECIAL. For instance, the results given by the
+above script can be obtained by doing:
+
+ cd /usr/src/usr.bin/spell
+ make LOCAL='/usr/local/dict/surnames /usr/local/dict/acronyms' \
+ SPECIAL=special.math
+ make install
+
+ Returning to the subject of the wordlists in /usr/dict, these are,
+in general, ordered as in sort -df. This makes no difference for
+spell's hashing process, but makes a difference for other commands,
+such as "look", that perform binary searches on the unhashed lists.
+
+Complaints, and any additional suggestions for words or wordlists,
+should be sent to me. I cannot fix bugs involving the code of "spell",
+but I am maintaining a list of these bugs, and of other ideas for
+improvement.

+--------------------------------------------------------------------
+FILES and subdirectories of /usr/share/dict:
+
+ words -- common words, and important technical terms from all
+ fields, that are spelled the same in British and American usage.
+ american -- spellings preferred in American but not British usage.
+ british -- spellings preferred in British but not American usage.
+ stop -- forms that would otherwise be derivable by "spell" from
+ words in one of the above files, but should not be accepted.
+ hlist -- hashed list, formed from the file "words" only.
+ hlista -- hashed list, formed from files {words,american,special/4bsd}.
+ hlistb -- hashed list, formed from files {words,british,special/4bsd}.
+ hstop -- hashed list, formed from file "stop".
+ web2 -- words from Webster's 2nd International (see WEB below).
+ web2a -- compounds and phrases from same source.
+ README -- this file
+ papers/ -- an (out-of-date specialized) bibliographical database,
+ used as the default by the program "refer".
+ special/ -- directory of less common terms from specialized fields.
+ It presently contains:
+
+ special/4bsd -- commands and system calls (from filenames in
+ /usr/share/man/man[1238n]), and builtin csh commands (named in
+ /usr/share/man/man1/csh.1) of the current version of 4bsd Unix.
+ (Supersedes old "/usr/src/usr.bin/spell/local".)
+ special/math -- some mathematical terms not in /usr/share/dict/words.
