[Apologies for disappearing, folks -- shock brought on by the phone bill.
;-) :-(  I'll try to get stuff out on a weekly basis from now on; perhaps
I'll be able to make other arrangements later.  But long-distance phone
calls to Virginia aren't cheap -- not on a daily basis.  ++bsa]

If you're planning a road trip, these macros for {n,t,di,etc}roff can
help.  You plug in the timepoints, distance between the timepoints,
your gas/oil costs per mile/km, and any other expenses (like food).
They print a formatted itinerary, including daily and grand totals of the
distance travelled and your expenses.  They're real nice for long trips
because it's easy to scope out an itinerary, let *roff calculate the
costs and distances, then rearrange things if you need to.
Plus, you get a nice itinerary printout to give friends/boss/parents.

I released the first version of these a few years ago.  This shar file
includes a man page with examples and a short sample itinerary for you
to format.  The shar file has a "tr" command in it, so if you're not
using a UNIX-like shell to un-shar it, see README.mti for help.
Enjoy, happy travels, etc.  Let me know how you like these.

XThe -mti macros make formatted travel itineraries.  This is version 2.0.
XI released an earlier version a few years ago.  This one has more
Xerror-checking and some bug fixes.
X
XThis shar file has:
X    tmac.ti        The *roff formatter macro package
X    mti.7        The manual page source for tmac.ti
X    sample.mti    Sample itinerary source file
X    README.mti    This file
X
XNOTE: The real tmac.ti file has some control-G characters in it.  But,
Xsome mail/news handlers strip out these control characters.  So, in
Xthis shar file, they're packed as capital Z characters.  A "tr" command
Xtranslates the Z's back to ^G's.  If you don't have "tr", use an editor
Xto change each Z into ^G (or any non-text character).
X
XThe sample.mti file is an itinerary I made up to show what a source
Xfile might look like.  I use one like it as a template; when I want a
Xnew itinerary, I just plug in the new starting day/date and change the
Xentries.  The comments in the file make it so easy that I never look at
Xthe man page.
X
XYou might start by un-sharing these files and formatting the man page:
X    Xroff -man mti.7 > somefile
X(If you need a formatted copy of the man page, let me know.)
X
XNext, try feeding the sample.mti file to your version of *roff.
XIf you put tmac.ti in your /usr/lib/tmac directory, you can do:
X    Xroff -mti sample.mti > itinerary
XOr, you can feed the macro file to *roff directly:
X    Xroff tmac.ti sample.mti > itinerary
X
XThen look at the output "itinerary" file.  It should have a title page
Xand two more pages.  The last day's entry should start:
X    DAY #5 OF TRIP: Monday, 5/22
Xand end:
X    TODAY: travel 473 miles in 13 hours for $15; other costs $8; total $23
X    TO DATE: 1331 miles, $215
Xif not, your formatter might have some math troubles.
X
XFinally, compare the itinerary to the sample output in the manual
Xpage.  If they have the same format, you're probably all set.  If you
Xhave trouble -- or, if you find bugs and fix them -- PLEASE tell me.
X
XBy the way, do whatever you want with these macros.  If you
Xredistribute them or edit them, please give me credit.  If you sell
Xthem, I wouldn't mind a share of the proceeds. :-)

X.SH DESCRIPTION
XThis package of \fInroff\fP\| and \fItroff\fP\|
Xmacro definitions makes formatted travel itineraries.
XThey're especially designed for road trips \(em
Xthrough they'll work for other kinds of travel, too.
X.PP
XYou give them the starting date, the time and mileage points you'll
Xhit each day, and each food/lodging expense you plan.
X(You also need to store the cost of travelling \(em usually fuel economy,
Xwith other fixed traveling expenses optional).
XThey'll output an itinerary that lists each timepoint and expense,
Xas well as daily and running totals of cost and distance.
X.SH EXAMPLE
XHere's a small part of a finished (fictional) itinerary, with `. . .' in place

X.PP
XThe source (unformatted) itinerary commands are flexible enough that it's easy
Xto rearrange your itinerary, try alternate routes, etc... after you've set up
Xan itinerary, the macros will calculate the total trip length and expenses.
X.PP
XFor example, here are the lines that produced the itinerary above.
XStart each day with \fI.SD\fR, use \fI.EN\fR for each entry, and
Xuse \fI.ED\fR at the end of each day.
XLodging expenses are marked with \fI.LO\fR, and \fI.FO\fR is for food:
X.nf
X.na
X.ft B
X.sp
X  .EN 6 PM "Camp near Dustbowl, NM"
X  .LO "Camping fee" 8
X  .ED 9
X  .SD
X  .EN 7 AM "NM-18, US-87 to Dalhart, TX" 129
X  .EN 9 AM "Time-zone change from MDT to CDT" 0
X  .EN 10 AM "TX-297, TX-281, US-22, US-83 to Canadian, TX" 135
X  .FO "Lunch in Canadian?" 6
X  .EN 1 PM "US-83, OK-54, I-40 to Oklahoma City" 140
X  .EN 4 PM "Arrive at Fred Smith's home" 0
X  .ED 8
X  .SD
X.ft P
X.fi
X.ad
X.sp
XThe argument to ED is the number of hours spent traveling that day.
XThe last argument to EN is the number of miles driven since the previous
Xtimepoint.
X.PP
XAll the \fI\-mti\fR macros are defined below.
XIt's okay to use most \fInroff\fP\| and \fItroff\fP\| requests
Xwith this package.
XHowever, watch out for fill- and non-fill modes, because
Xthe macros switch back and forth between the two modes.
XSee the individual macro descriptions below.
XAlso, be careful about setting number and string registers:
Xthe macros use a few of them (see the list below).
X.PP
XFont and point size changes with \ef and \es are also allowed;
Xfor example, ``\efIword\efR'' will italicize \fIword.\fP
X.SH OPTION
XIf you use \fI\-rQ2\fR on the command line, the macros won't print the
X\fBTODAY:\fR and \fBTO DATE:\fR summaries at the end of each day.
XOther command-line options go directly to \fInroff\fR or \fItroff\fR.
X.SH REGISTERS AND MACROS
XHere's a summary of the number and string registers \(em and the macros \(em
Xthat make up the
X.I \-mti
Xmacros.
XAfter the summary are detailed explanations and examples of each.
XSo, beginners can safely skip this reference section for now.

X.SH "SOURCE-FILE DESCRIPTION"
XThis part of the manual describes what you should put in a
Xsource (unformatted) itinerary file.
X.sp 2
XThe \fBFIRST SECTION\fR of each file stores numbers and strings (words) that
Xset the initial conditions (starting date, fuel economy, etc.).
XYou can put these first few lines in any order, as long as they're all at
Xthe top of the file.
XIndividual descriptions:
X.TP 12
X.B \&.ds DY Day
X.I Required:
Xday of the week that trip starts.
XFirst letter of day must be capitalized, rest lower-case.
XNo abbreviations.
XExample:
X.br
X    \fB.ds DY Saturday\fR
X.TP 12
X.B \&.nr DT Date
X.I Required:
Xnumerical date when the trip starts.
XFor example, if the trip started on August 15th:
X.br
X    \fB.nr DT 15\fR
X.TP 12
X.B \&.nr MN Month\fR
X.I Required:
Xnumerical month that the trip starts (January = 1, February = 2, etc.).
XExample:
X.br
X    \fB.nr MN 8\fR
X.TP 12
X.B \&.nr DU xx
X.I Required:
XDistance you can travel for each currency-unit you spend (in the U.S.,
Xnumber of miles that cost one dollar; in France, kilometres you can travel for
Xone Franc; etc.).
XThis rather weird number was designed to get around a problem:
X.I nroff
Xand
X.I troff
Xcan't do decimal arithmetic -- only integers.
XHere are two examples that should clear things up:
X.sp
XOn your trip across the U.S., you guess that you'll get 30 miles/gallon,
Xand that gas will cost $1.25 per gallon.
XSo, the miles per dollar are:
X.ft B
X.nf
X.na
X.sp
X        30 miles/gallon
X    -----------------------\0=\024\0miles/dollar
X      1.25 dollars/gallon
X.ad
X.fi
X.ft P
X.sp
X\&...which means that you'd put this line in your source file:
X.br
X    \fB.nr DU 24\fR
X.sp
XOr, if you were driving across Europe, getting 17 kilometres/litre and
Xspending DKK 6- per litre, the setting of \fBDU\fP should be 17 divided by 6,
Xor about 3 kilometres per DKK.
XSo, you'd put this line in your itinerary:
X.br
X    \fB.nr DU 3\fR
X.TP 12
X.B \&.nr FD 2x
X.I Required:
XNumber of days in February \(em 28 or 29.
XTells program whether this is a leap year.
XMust be set, even if your itinerary doesn't include February.
XFor example, if there are 28 days in February during the year of your trip (a
Xnon-leap year):
X.br
X    \fB.nr FD 28\fR
X.sp
XIf your trip crosses two years but only one February, set FD for the
Xnumber of days in the February when you'll be traveling.
X.TP 12
X.B \&.ds TI TITLE
X.I Optional:
Xtitle for upper right-hand corner of each page.
XIf you don't define it, it'll be blank.
XHere's how you could define it:
X.br
X    \fB.ds TI CROSS-COUNTRY TRIP\fR
X.TP 12
X.B \&.ds CS xxx
X.I Optional:
Xcurrency symbol (default = \fB$\fR).
XCan be set to other currency names, like \fISKR\fR, this way:
X.br
X    \fB.ds CR SKR\fR
X.sp
XThis is used in the \fBTODAY:\fR and \fBTO DATE:\fR lines printed at the end
Xof each day.
X.sp
XNormally, the currency symbol and the cost are printed touching each other,
Xlike \fB$123\fR or \fBhfl162\fR (Dutch Guilder).
XIf you want space after the currency symbol (like \fBhfl\ 162\fR),
Xuse a backslash and a trailing blank when you define the currency symbol.
XFor example,
X.br
X    \fB.ds CR hfl\e\ \fR
X.br
XJust be sure to put the blank after the backslash!
X.TP 12
X.B \&.ds US units
X.I Optional:
Xthe units of distance, short name.
XThe default is \fImi\fR (miles).
XTo change it to, say, \fIkm\fR:
X.br
X    \fB.ds US km\fR
X.TP 12
X.B \&.ds UL units
X.I Optional:
Xthe units of distance, long name, plural.
XThe default is \fImiles\fR.
XTo change it to, say, \fIkilometers\fR:
X.br
X    \fB.ds UL kilometers\fR
X.PP
X.sp
XThe \fBTITLE SECTION\fR is usually short.
XIt starts with the \fI.ST\fR macro, and ends with \fI.ET\fR.
XIf you want other text on the title page, you can put it between the macro
Xcalls.
X.TP 12
X\fB\&.ST\0"First line"\0"Second line"\fR
X.I Required:
Xafter you've set the number and string registers in the first section,
Xyou must use \fI.ST\fR (start title page).
XIf you want a title on the first page, it can have one or two lines...
Xthe macros will make it in larger type and center each line.
X.sp
XQuote each line of the title, and put the text on the same line as
Xthe \fI.ST\fR call.
XIf you don't want one or both lines, just leave them out.
XExample:
X.br
X    \fB.ST\0"Our trip"\0"to Lower Slobovia"\fR
X.sp
XAfter the \fI.ST\fP, you can put text for the title page.
XYou'll usually want to skip down a few lines (say, \fB.sp 5\fR)
Xbefore starting the text.
XThe title page is made in no-fill mode, so what you type in will be exactly
Xwhat appears on the title page.
XYou can start fill mode (\fB.fi\fR and maybe \fB.ad\fR), but BE SURE to
Xgo back to non-fill mode (\fB.nf\fR) before you use the \fB.ET\fR macro!
X.TP 12
X.B \&.ET
X.I Required:
XAt the end of the title page (after the \fB.ST\fP and the optional text),
Xend the title page with \fB.ET\fR.
X.PP
X.sp 2
XThe last part of the file are the \fBDAILY ENTRIES\fR, which are enclosed
Xwith \fB.SD\fR and \fB.ED\fR macro calls.  Here are the details:
X.TP 12
X.B \&.SD
XEach day's entry must start with the \fI.SD\fR macro.
XPut it on a line by itself.
X.TP 12
X\fB\&.EN time AM/PM "description" distance
X.I Required:
XFor each timepoint in a day, use the \fI.EN\fR (entry) macro.
XThe first argument is the clock time, a number between 1 and 12 (though
X24-hour time will work fine here).
X.sp
XIf you use a 12-hour clock, the second argument should be AM, PM, NOON, or
Xsomething like that.
XOn a 24-hour clock, use your imagination.
X.sp
XYou should put quotes around the third argument, which is usually the
Xdescription of a route you're taking since the last timepoint.
XIt can also hold the name of a destination.
X.sp
XThe fourth argument must be a number \(em the distance travelled
Xduring this entry.
X(Or, in other words, the distance travelled since the previous entry.)
X.sp
XHere's an example.
XIt's 10 AM and you're about to leave Auckland, New Zealand for a trip to
XRotorua.
XThe trip is via highways 3 and 12 and is 200 kilometres long (I'm making this
Xup!).
XYou'd write this \fI.EN\fP macro:
X.br
X    \fB.EN\010\0AM\0"Hwys. 3, 12 to Rotorua"\0200\fR
X.sp
XYou can omit the fourth argument in places where it isn't needed:
X.br
X    \fB.EN\04\0PM\0"Arrive in Timbuktu"\fR
X.TP 12
X\fB\&.FO "description" cost\fR
X.I Optional:
XWhen you plan to spend money for food, note it with \fI.FO\fR.
XYou must use \fI.FO\fR between a pair of \fI.SD\fR and \fI.ED\fR macros.
X.sp
XExample: in the middle of the day, you plan to spend $55 for lunch for your tour
Xgroup.
XYou might use this entry:
X.br
X    \fB.FO "lunch at Grease Cafe, El Paso" 55\fR
X.TP 12
X\fB\&.LO "description" cost\fR
X.I Optional:
XWhen you plan lodging expenses, note them with \fI.LO\fR.
XUse \fI.LO\fR between a pair of \fI.SD\fR and \fI.ED\fR macros.
X.sp
XExample: You'll be staying at the Waldorf-Astoria tonight, spending $1000.
XYou might use this entry, including the phone number for convenience:
X.br
X    \fB.LO "Waldorf-Astoria, 212/345-2999" 1000\fR
X.TP 12
X\fB\&.OE "description" cost\fR
X.I Optional:
XThe \fI.OE\fR (capital letter O) macro is for expenses besides food and
Xlodging.
XYou have to use \fI.OE\fR between a pair of \fI.SD\fR and \fI.ED\fR macros.
X.sp
XExample: You expect a transmission overhaul in Nairobi:
X.br
X    \fB.OE "Rebuild transmission" 550\fR
X.TP 12
X.B \&.ED total-time
X.I Required:
XAt the end of each day's entries, use \fI.ED\fR with the total time spent
Xtraveling that day.
XThis is usually the elapsed time between the first and last timepoints in the
Xday \(em unless you're crossing time zones.
X.sp
XExample: If you started traveling at 9 AM and finished at 5 PM, that's 8
Xhours of traveling:
X.br
X    \fB.ED 8\fR
X.TP 12
X.B \&.HL
X.I Optional:
XDraws a horizontal dashed line across the page.
X.TP 12
X.B lines with no macros
XIf you don't use a macro on a line, the line will be copied directly
Xto the itinerary without filling, adjusting, or wrapping.
XThe lines may look better if you indent them with a tab character.

X'\"      ti travel-itinerary macros for nroff/troff
X'\"    Jerry Peek; Syracuse, NY; [e-mail], [e-mail]
X'\"
X'\"    If you make changes or bug fixes, please send me a copy so I can
X'\"    pass them on to other people...
X'\"
X.nf
X.na
X'\" Set line length to 8 inches (nroff only) so ".EN" entries can be longer:
X.nr St 0    \" dumb register that counts use of ST and ET macros
X.if n \{\
X.ll 8i
X.lt 8i \}
X.nr MI 0    \" total miles/kilometers
X.nr MT 0    \" miles or km today
X.nr CO 0    \" total cost
X.nr CT 0    \" cost today
X.nr DA 0 1    \" total number of days and amount (1 day) to increment by
X'\" Units to use: miles or km.  UL is long, for daily summaries; US is short,
X'\" used on each line.  User can re-define in file; should be lower-case:
X.ds UL miles
X.ds US mi
X'\" Currency symbol.  User can re-define in file.
X'\" Can have several characters, including trailing blanks:
X.ds CS $
X'\" Start-itinerary macro.  $1 = title for first page.
X'\" $2 = optional second title line.
X.de ST
X'\" Check flag to see if user has already invoked ST macro.  If so, scream.
X'\" If not, set flag:
X.if !\\n(sT=0 .ER "only one .ST per file, please."
X.nr sT 1
X.if !\\n(eT=0 .ER "You must use the .ET macro after the .ST"
X.if \\n(.$>2 .ER ".ST: you can't use more than two arguments."
X'\" Because first .SD will increment starting day, decrement it here.
X'\" Also, be sure starting day name is valid (if valid, set cK to 0):
X.nr cK 1
X.if '\\*(DY'Sunday' \{\
X.ds Dy Saturday
X.nr cK 0\}
X.if '\\*(DY'Monday' \{\
X.ds Dy Sunday
X.nr cK 0\}
X.if '\\*(DY'Tuesday' \{\
X.ds Dy Monday
X.nr cK 0\}
X.if '\\*(DY'Wednesday' \{\
X.ds Dy Tuesday
X.nr cK 0\}
X.if '\\*(DY'Thursday' \{\
X.ds Dy Wednesday
X.nr cK 0\}
X.if '\\*(DY'Friday' \{\
X.ds Dy Thursday
X.nr cK 0\}
X.if '\\*(DY'Saturday' \{\
X.ds Dy Friday
X.nr cK 0\}
X.if \\n(cK .ER ".ST: day name DY is missing or invalid."
X.rr cK
X.rm DY
X.if \\n(DU<1 .ER ".ST: DU undefined or less than 1.  Can't calculate fuel cost."
X.if (\\n(FD<28):(\\n(FD>29) .ER ".ST: FD undefined, or not 28 or 29."
X.if (\\n(MN<1):(\\n(MN>12) .ER ".ST: MN (\\n(MN) undefined, less than 1 or more than 12."
X.if \\n(DT<1 .ER ".ST: starting date DT is less than 1 or not defined."
X'\" Put DT (starting date: 1, 2, ..., 31) in Dt (date register);
X'\" set Dt to one day before start of trip because first .SD will increment it:
X.nr Dt \\n(DT-1 1
X.rm DT
