mim runs scripts from a specification file which can be thought
of as an extremely limited Makefile. Neither make variables nor
dependencies are supported. By default the file 'Mimfile' is read.
An example:
hello:
echo hello $1
clean:
rm -rf *
The command 'mim' or 'mim hello' will echo 'hello'. Unlike 'make'
arguments after the first are available to the script; they don't
specify additional targets.
mim isn't enabled by default. Enabling it increases the size of the
binary by about 500 bytes.
