Make wrapper - Guesses what I meant when there was no Makefile in the current directory.

make-wrapper.bash

function yellow { echo -e "\e[33m$@\e[0m"; }

# Wrapper around make, which covers building different project types, when an
# actual Makefile isn't present.
function make {
    if [[ -e Makefile ]]; then
        yellow "[make] found Makefile"
        /usr/bin/make $@
    else
        yellow "[make] No Makefile found"
        if [[ -e setup.py ]]; then
            yellow "[make] python setup.py build_ext -i"
            python setup.py build_ext -i
        else
            # Compile most-recently modified tex file, if one exists.
            local tex=`ls -t *.tex 2>/dev/null |head -n1`
            if [[ -n $tex ]]; then
                yellow "[make] latexmk $tex"
                latexmk -pdf $tex
                local pdf=`echo $tex |sed -e 's/tex$/pdf/'`
                xdg-open $pdf   # or whatever file opening utility you like.
            fi
