#
# This module finds if Latex is installed and determines where the
# executables are. This code sets the following variables:
#
#  LATEX_COMPILER        = the full path to the LaTeX compiler
#  PDFLATEX_COMPILER     = the full path to the PdfLaTeX compiler
#  BIBTEX_COMPILER       = the full path to the BibTeX compiler
#  MAKEINDEX_COMPILER    = the full path to the MakeIndex compiler
#  DVIPS_CONVERTER       = the full path to the DVIPS converter
#  PS2PDF_CONVERTER      = the full path to the PS2PDF converter
#  LATEX2HTML_CONVERTER  = the full path to the LaTeX2Html converter
