XLike most people these days, I'm looking for ways to make my computing
Xenvironment more efficient.  This environment consists of a 486, a 386,
Xand a 386SL laptop, all of which run Taylor uucp under Linux.  The 386
Xlaptop gets used a lot, since it goes wherever I go and I answer a lot
Xof news and email every day.  Often, I must use other people's facilities
X(phone lines and such) to send out replies and post news if I'm not at home.
XSince it's not fair to the client for them to pay for my zone calls back
Xto my home in Fremont, I place the calls on my phone card.  Unfortunately,
XPacBell is very proud of the services they offer, especially in regards
Xto this convenience of automatically charging calls to my house wherever I
Xmay be.  Considering that this can be very expensive to do, I searched for
Xa way to cut my phone bill down to something I could afford to pay each
Xmonth without fainting every time I saw the bill.
X
XThe first thing I did was to go out and plunk $195 for a 14.4KB modem.
XThat helped, but C-News is very slow on my laptop, and batching articles
Xis even slower, and email (of course) isn't batched at all.  Even with
XMNP5 compression turned on, this doesn't make for a very efficient setup,
Xeven at high speeds.
X
XPlaying around with uucp told me that the line turnaround wasn't that much
Xoverhead, nor was sending the C./X. files (the execute files) - the real
Xoverhead was sending out uncompressed news and especially email, since
XI subscribe to several mailing lists and digests can run quite large.
X
XI looked at uubatch, but the most current version I could find (1.05) was
Xnot compatible with Taylor uucp (and I had no other alternative), so I
Xdecided to write my own.  Experiments with "gzip -9" convinced me that
Xthat was the way to go, since gzip gives email and news 60 to 75 percent
Xcompression, which would tend to cut one's phone bill significantly.
X
XYou hold in your mailbox (or news reader) the end result of that effort.
XBear in mind that (1) this is a "first cut" and while it is unlikely that
Xthere are very many bugs, there are certainly places where the programs could
Xbe improved and tuned.  Suggestions and comments are welcome!
X
XTo install:
X
X	1.	Feed this to shar.
X	2.	Look at the Makefile.  Make sure that the paths for
X		things are set up correctly.
X	3.	Look at uucomp.h and make sure that the path and
X		options for COMPRESS/UNCOMPRESS are set up properly.
X	3.	Type "make".  This will make uucomp, crmail, and crnews
X		and will place them in /usr/bin.  Move Compress into
X		/usr/lib/uucp.
X	4.	Make an entry in crontab to do
X			/usr/lib/uucp/Compress site1 site2 site3...
X		occasionally.  It is suggested that this be done fairly
X		frequently.  Alternately, you could set up a login shell
X		for selected sites to run uucomp every time that site
X		logged in.
X	5.	Don't forget to add /usr/bin/crmail and /usr/bin/crnews
X		to the list of programs allowed to be executed in your
X		Permissions file (if running HDB UUCP), or whatever is
X		appropriate for your version of uucp.
X
XEnjoy!  Any questions or comments can be sent to erc@apple.com.
X
XNote:  This is tuned for Taylor uucp, but would not be particularly
Xdifficult to adapt to other version of uucp.  See the file INTERNALS for
Xdetails of how this works.
