.SH DESCRIPTION
|
|
.I MzScheme
|
|
is the Rice University PLT
|
|
Scheme implementation. It implements the language as
|
|
described in the
|
|
.I Revised^4 Report on
|
|
.I the Algorithmic Language Scheme\|\c
|
|
, plus numerous extensions.
|
|
.I MzScheme
|
|
is the underlying implementation for
|
|
.I DrScheme
|
|
and
|
|
.I MrEd.

Miscellaneous switches:
|
|
.TP
|
|
.B \--
|
|
.br
|

No argument following this switch is used as a switch.
|

.PP
|
|
Multiple single-letter switches can be collapsed, with arguments placed
|
|
after the collapsed switches; the first collapsed switch cannot be
|
|
.BR -- .
|
|
E.g.:
|
|
.B -vfme file expr
|
|
is the same as
|
|
.B -v -f file -m -e
|
|
.BR expr .
|
|
.PP
|
|
Extra arguments following the last switch are put into the Scheme global
|
|
variable `argv' as a vector of strings. The name used to start
|
|
.I MzScheme
|
|
is put into the global variable `program' as a string.
|
|
.PP
|
|
Extra arguments after a
|
|
.B --restore
|
|
file are returned as a vector of
|
|
strings to the continuation of the `write-image-to-file' call that created
|
|
the image.
|
|
.PP
|
|
Expressions/files are evaluated/loaded in order as provided.
|
|
.PP
|
|
The current-library-collections-path is automatically set before any
|
|
expressions/files are evaluated/loaded, unless the
|
|
.B -x
|
|
or
|
|
.B --no-lib-path
|
|
switch is used.

.SH FILES
|
|
The file "~/.mzschemerc" is loaded before any provided
|
|
expressions/files are evaluated/loaded, unless the
|
|
.B -q
|
|
or
|
|
.B --no-init-file
|
|
switch is used. (Under Windows and MacOS, "mzscheme.rc"
|
|
is loaded from the start-up working directory.)
|
|
.PP
|
|
.I MzScheme
|
|
looks for the library collections directory using the
|
|
following search path:
|
|
.IP
|
|
If
|
|
.I MzScheme
|
|
was invoked with an absolute pathname, the directory
|
|
of the invoked executable is checked. If the executable
|
|
is a link, the directory of the referenced file is also
|
|
checked, recursively following links.
|
|
.IP
|
|
If
|
|
.I MzScheme
|
|
is invoked with a relative pathname, the
|
|
directories in the PATH environment variable containing
|
|
a file with the name of the program as invoked (usually
|
|
"mzscheme") are checked. Links are followed as in the
|
|
first case.
|
|
.IP
|
|
The path in the environment variable MZCOLS is tried.
|
|
.IP
|
|
The path in the environment variable PLTHOME is checked
|
|
for a "mzscheme" and then "collects" subdirectory.
|
|
.IP
|
|
The "/usr/local/lib/plt/mzscheme/collects" directory is
|
|
tried.

.SH AUTHOR
|
|
.I MzScheme
|
|
was implemented by Matthew Flatt (mflatt@cs.rice.edu).
|
|
It uses the conservative garbage collector implemented by Hans
|
|
Boehm and extended by John Ellis. MzScheme was originally based
|
|
on libscheme, written by Brent Benson.
