.SH DESCRIPTION
|
|
.I MrEd
|
|
is Rice University's Programming Languages Group's GUI
|
|
execution engine.
|
|
.I MrEd
|
|
runs on a variety of platforms.
|
|
.PP
|
|
The -s flag directs
|
|
.I MrEd
|
|
to load the startup system from
|
|
a particular file. This overrides the system directory
|
|
search path described below in FILES and must come before all other
|
|
arguments.
|
|
.PP
|
|
The -q or --no-init-file flag prevents
|
|
.I MrEd
|
|
from loading
|
|
the user's startup file ".mredrc" in the user's home
|
|
directory.
|
|
.PP
|
|
multiple -f
|
|
and -e flags can be specified. For each -e flag, the corresponding
|
|
expression is evaluated. For each -f flag, the corresponding file
|
|
is loaded (with its directory as the working cirectory).
|
|
.PP
|
|
If a file appears on the command line with no switches, then it is opened
|
|
for editing in
|
|
.I MrEd.
|
|
The -- flag means to treat the next argument as a file
|
|
to be opened for editing, even if it is "-e" or "-f".
|
|
.PP
|
|
The -nu flag specifies a non-unit startup. See the Toolbox Manual for more
|
|
details on
|
|
.I MrEd's
|
|
startup and how to build your own application with
|
|
.I MrEd.
|
|
.PP
|
|
Once all command line arguments are handled the scheme procedure
|
|
mred:startup is called. This procedure is defined by the standard
|
|
system, but it can be redefined with the -f or -e flags for
|
|
application-specific startup sequences.

.SH FILES
|
|
If the -s flag is not specified,
|
|
.I MrEd
|
|
looks for its standard system file "mrsystem.ss" with the following
|
|
search path:
|
|
.IP
|
|
* the search path defined by the MREDSYS system evironment
|
|
variable
|
|
.IP
|
|
* In PLTHOME/mred/system where PLTHOME is replaced with the value of the
|
|
PLTHOME environment variable.
|
|
.IP
|
|
* "/usr/local/lib/plt/mred/system"
|
|
.IP
|
|
* "/usr/lib/plt/mred/system"
|
|
.IP
|
|
* "/usr/local/lib/mred/system"
|
|
.IP
|
|
* "/usr/lib/mred/system"
|
|
.PP
|
|
|
|
The standard system loads in the core or the mzlib library,
|
|
using the following search path:
|
|
.IP
|
|
* "../mzlib"
|
|
.IP
|
|
* "../mzscheme/mzlib"
|
|
.IP
|
|
* "../../mzscheme/mzlib"
|
|
.IP
|
|
* "PLTHOME/mzscheme/mzlib", where "PLTHOME" is replaced
|
|
with the value of the PLTHOME environment variable.
|
|
If the environment variable is undefined,
|
|
"/usr/local/lib/plt/" is used
|
|
.PP

|
the on-line documentation has been installed locally.
