makefile

#
# Makefile for miniTeX
#
# Compiler: GCC
# Other requirements: Flex, Bison
#
# NB: On Windows, MSYS make must be used. MinGW make and Microsoft's nmake do not support ifeq and the makefile leads to errors. Also rm was used instead of del etc.
#
# To download MSYS make on Windows, see https://www.msys2.org/
