+In order to use minim-mp as a stand-alone metapost compiler, you will have to
+generate the appropriate format files. For metapost with plain tex, say
+
+ luatex --ini minim-mp.ini
+
+For metapost with latex, say
+
+ luatex --ini minim-lamp.ini
+
+The resulting format (.fmt) files will be found if they are either in the same

+\section Logs and debugging % 1
+
+Metapost log output of every processed chunk of metapost code will be printed
+to the main log file in a quoted form.
+The logs will be duplicated to the terminal if an error occurs or if the
+variable ⟦*M.on_line⟧ is ⟦true⟧ (the default is ⟦false⟧, but set to ⟦true⟧ in
+the stand-alone format files).
+Because a single error message might trigger many others, log output to the
+terminal (but not the log file) will be cut after a certain number of errors:
+this behaviour is governed by the ⟦*M.max_errprint⟧ variable (default ⟦1⟧; set
+to ⟦0⟧ to disable).
+
+You can enable (global) debugging by saying ⟦*debug_pdf⟧ to metapost,
+⟦*\debugmetapost⟧ to tex or ⟦*M.enable_debugging()⟧ to lua. This will write
+out a summary of metapost object information to the pdf file, just above the
+pdf instructions that object was translated into. For this purpose, the pdf
+will be generated uncompressed. Additionally, the metapost code itself will be
+echoed to the log, as well as ⟦runscript⟧ and ⟦maketext⟧ invocations, and
+a small summary of every generated image will be written to log and terminal.
+
+For debugging the results of ⟦maketext⟧ and the like, you can set the
+⟦*debug_tex_bboxes⟧ variable to ⟦true⟧ and have their resulting bounding boxes
