`inimpost' invocation
=====================

  `inimpost' is the "initial" form of MetaPost, which does lengthy
initializations avoided by the "virgin" (`vir') form, so as to be
capable of dumping `.mem' files (Note: Memory dumps).  For a detailed
comparison of virgin and initial forms, see Note: Initial and virgin.

  For a list of options and other information, see Note: mpost
invocation.

  The only memory dump file commonly used with MetaPost is the default,
`plain.mem', also known as `mpost.mem' (again, Note: Memory dumps).
It is created by default during installation, but you can also do so by
hand if necessary (e.g., if a MetaPost update is issued):
     inimpost '\input plain dump'

(The quotes prevent interpretation of the backslashes from the shell.)
Then install the resulting `plain.mem' in `$(memdir)'
(`/usr/local/share/texmf/web2c' by default), and link `mpost.mem' to it.

  MetaPost also provides a mem file with all the features of plain
Metafont, called `mfplain.mem'.  You can create that in the same way;
just replace `plain' in the above command with `mfplain'.
`mfplain.mem' file lets you directly process Metafont source files with
MetaPost, producing character proofs (one file for each character)
similar to those produced with Metafont in proof mode and GFtoDVI
(Note: gftodvi invocation).
