#
# letr - a Unix shell script for printing a letter with an addressed
# envelope, using TeXsis (the TeX macros for physicists). The syntax is:
#
# letr [ -q ][ -Pprinter ] [ dvips flags ] [ filename ]
#
# where "filename" is the name for your TeX job. The TeX instructions
# for creating your letter will be put in the file filename.tex, while
# the instructions for creating the printed envelope will be in the
# file filename.env. If no name is given the default is "TeXletter".
#
# You first edit your letter with your default EDITOR, then it is run
# through TeXsis. You can preview the letter, and then choose whether
# or not to print it, and whether or not to print the addressed envelope.
#
# Use the -q flag to bypass the editor, and -P to specify an alternate
# printer. All other flags are passed to dvips. So, for example, if
# you give the -m flag it will go to dvips and the letter (not just the
# envelope) will be printed in manual feed mode, so you can put your own
# paper in the printer for it.
#
# To get the envelope to print in landscape mode and with manual feed
# we call dvips explicitly. If you need to, change the DVIPS command
# and ENVFLAGS below to match your local site configuration.
