# Makefile for SFLC Presentation
#
#  There are two settings that the user should be concerned with:
#      PRESENTATION_BASE, and SFLC_REPOSITORY_PATH.  Details on those are below.
#
#  Once those variables are set properly, just typing "make" should get you
#  a PDF, Postscript, and HTML version of your paper.

# You can change the PRESENTATION_BASE below, or if you like, or set it as
# an environment variable before you type make.

#  $ export SFLC_REPOSITORY_PATH=/home/USER/path/to/my/checkout
# or here in the Makefile with:
#  SFLC_REPOSITORY_PATH := /home/USER/path/to/my/checkout

# This should be the path to your checkout of the repository.  Under that
# directory, you must have a checkout of /Admin/Forms/TeX.
