Makefile for LaTeX

This aims to be a generic Makefile to compile LaTex sources to PDF files.

For each PDF the Makefile assumes that there is one main LaTeX source file, by default indicated by an existing empty file <sourceFile>.latexmain, as it is for example also used by the vim-latexsuite. There is also a list of input files which the main source files depend on. By default, the input files are determined via a wildcard ???-*.latex, so that e. g. the main file main.latex may include files like 000-introduction.latex, 100-first_chapter.latex via \input{...}.

The Makefile employs:

• Two modes draft and final. In draft mode the Makefile will define the macro \draft which can be used to conditionally include parts of your document only in draft versions:

   \ifdefined\draft
   	% draft-specific LaTeX code
   \fi
  

  You can use it for example in combination with the todonotes package:

   \ifx \draft \undefined
   	\usepackage[disable]{todonotes}
   \else
   	\usepackage{todonotes}
   \fi
  

• If placed inside of a git repository, the Makefile will define the macro \versiontag which can be used to indicate the git revision from which the document was generated.

  The macro will contain the output of:

   $ git describe --all --tags --long
  

• An optional list of subdirectories SUBDIRS to descend into and call make subsequently.

• clean target which deletes all temporary files that are created by LaTeX during compilation.

• distclean target which additionally to clean also deletes the compiled PDF files.

• todo target which greps all LaTeX files for the strings TODO and FIXME.

• spellcheck target which invokes hunspell for all LaTeX files with the language as specified in the variable LANGUAGE.
