dune build should be enough to compile chamelon, with the OCaml 4.14 compiler.

Basic usage is: chamelon -c "[compile command]" -e "[error]" input.ml

This will execute the command on input.ml, and produce a minimized output input_min.ml such that the output of the command still contains [error].

The following options are also available:

• -o [file]: this will use [file] as the ouput instead of the default - that is, suffixing the input file with _min. Inplace minimization can be achieved by setting the output file to the input file.
• -t [command]: this uses [command] input.ml to produce a .cmt file. This is necessary when the given command is not a compilation command. This is also useful if you want to minimize a file when the compilation command produces .cmt files incompatible with the version of OCaml chamelon is compiled with.
• -m [minimizers]: this runs the minimizers from the comma-separated list of minimizers given as arguments instead of the default iteration order.
