.

is a Mac implementation of John Hobby's MetaPost program for producing PostScript pictures using a ${\logo METAFONT\null}$ -like language. The PostScript files created by MetaPost don't contain a PICT 256 resource, so you'll need a PostScript printer to print a DVI file that includes such files. The application should be kept in the same folder as , along with the MetaPost folder which contains these subfolders:

Configs: contains the configuration files used by , especially the Default file which is loaded when starts up. Before using MetaPost, examine the supplied parameters in the Default file and make sure the search paths for TFM/VF files match those used by . Also read the comments at the bottom of the file.
Docs: contains John Hobby's documentation for MetaPost. Before printing anything, select ``MetaPost'' from the Help menu and carry out the given steps.
Help: contains the files used in 's Help menu.
Inputs: contains *.mp files.
Mems: contains mp.pool (read by INIMP) and Plain.mem. Mem files are the MetaPost equivalent of ${\logo METAFONT\null}$ 's base files. Use INIMP to build mem files.

includes two supporting tools, MPtoTeX and DVItoMP. If you are using System 7 or later then you won't need to run these tools manually because will call them automatically if your .mp file contains btex ...etex or verbatimtex ...etex sections. Such sections contain TEX/L^ATEX code, so will also call in between MPtoTeX and DVItoMP.
