+# Makefile for generating LaTeX documents
+#-----------------------------------------------------------------------
+#
+# This is a simple makefile for generating LaTeX documents. It will
+# run bibtex, generate eps from xfig figures, and make pdfs. The
+# makefile supports builds in non-source directories: just make a
+# build directory, copy the makefile there, and change the srcdir
+# variable accordingly.
+#
+# Note that the makefile assumes that the default dvips/ps2pdfwr 
+# commands "do the right thing" for fonts in pdfs. This is true on 
+# Athena/Linux and Fedora Core but is not true for older redhat installs ...
+#
+# At a minimum you should just change the main variable to be
+# the basename of your toplevel tex file. If you use a bibliography 
+# then you should set the bibfile variable to be the name of your
+# .bib file (assumed to be in the source directory).
+#
+
+# Targets:
+#  (none)	makes PDFs in output/
+#  clean	removed everything except PDFs in output/
+#  clean-all	removed everything in output/
+
+# Directories relative to the top level:
+outdir    = output
+srcdir    = src
+# Relative to output:
+relsrcdir = ../$(srcdir)
+
+docs_with_bib = power-spec
+docs_without_bib =
+
+srcs = $(wildcard $(srcdir)/*.tex)
+figs = $(wildcard $(srcdir)/figs/*)
+bibs = $(srcdir)/power-spec.bib
+
+#=======================================================================
+# You shouldn't need to change anything below this
+#=======================================================================
