In Lisp code, COMMAND is similar to what you pass to
`make-process', except as follows. Normally, the contents of the
current buffer are passed to the command on stdin, and the output
is read from stdout. However, if you use the symbol `input' as
one of the elements of COMMAND, then the contents of the current
buffer are written to a temporary file and its name is
substituted for `input'. Also, if you use the symbol `output' as
one of the elements of COMMAND, then it is substituted with the
name of a temporary file. In that case, it is expected that the
command writes to that file, and the file is then read into an
Emacs buffer. Finally, if you use the symbol `npx' as one of the
elements of COMMAND, then the first string element of COMMAND is
resolved inside node_modules/.bin if such a directory exists
is read from stdout. However, if you use the symbol `file' as one
of the elements of COMMAND, then the filename of the current
buffer is substituted for it. If you instead use the symbol
`input' as one of the elements of COMMAND, then the contents of
the current buffer are written to a temporary file and its name
is substituted for `input'. Also, if you use the symbol `output'
as one of the elements of COMMAND, then it is substituted with
the name of a temporary file. In that case, it is expected that
the command writes to that file, and the file is then read into
an Emacs buffer. Finally, if you use the symbol `npx' as one of
the elements of COMMAND, then the first string element of COMMAND
is resolved inside node_modules/.bin if such a directory exists
anywhere above the current `default-directory'.
