Instructions to do spell check in latex

It seems unreasonable to implement spell checking as a LaTeX package when there are excellent spell checkers for the terminal that can be incorporated into the compilation process. Before you compile you can do

aspell -t -c file.tex

or

ispell -t file.tex

Either lets you interactively spell check the whole file. The -t option is to tell the spell checker that the file is in TeX or LaTeX format so that it will ignore macros. To combine this with the compilation process you can invoke them after each other such as

aspell -t -c file.tex && pdflatex file.tex
