Subject: Addition to archive blurb.

Fellow CP/Mers - Earl Boebert at HI-MULTICS has suggested that since there
will be greater use of CP/M library (LBR) files in order to conserve space on
the MICRO: disk-pack at SIMTEL20, it would be helpful to include in the blurb
a description of these files.  I heartily agree.  Thanks for the suggestion,
Earl.  Here is the addition.  It goes in the FILE TYPES section, and I have
included some of the surrounding text, so that those who care to do so can
insert it into their copies of the blurb.


as a binary file, and then unsqueezed.  The unsqueezing can be done on a CP/M
system using USQ-20.COM (or whatever is the current version from directory
<CPM.SQUSQ>), or there are several host-based unsqueezers in the <CPM> and
<UNIX> archives (see for example, directories <CPM.TOPS-20> and <UNIX.CPM>).

     CP/M library files, which can be identified by their ".LBR" extensions,
combine several regular CP/M files into a single binary file which contains
an internal directory of its contents.  They are created using the CP/M
library utility, LUxxx.COM (where "xxx" is three digits giving the current
version number), or some other compatible utility.  Because these are binary
files, they are stored in ITS binary format, and they must be retrieved using
the special procedures described elsewhere in this message.  LUxxx and a newer
compatible program called NULUxx (where "xx" is the version) can be found in
directory MICRO:<CPM.CPMLIB>.  C-language source code for a compatible UNIX
utility called LAR (library archiver) is in directory MICRO:<UNIX.CPM>.

     Although the type of storage used for a particular file can usually be
inferred from the file-name, this is not always true.  It is a good idea to
check the appropriate "crclst" file to ascertain the storage format used for
each file of interest.  This applies to all of the archives except <UNIX> and
<ADA>, where ALL files are presently stored in ASCII.  Now, and for the
