.PP
Without arguments,
.I helpmidas

Some of these definitions can be modified with arguments in the command line of

line are taken with preference to environment variables.

(defined internally in the script).

.IP "\fB-d\fp \fIdisplay\fp"

be aware of allowed access to a remote X server using the
.IR xhost (1)
command.)
.IP "\fB-m\fp \fImid_work\fp"
Specifies the MIDAS startup directory (default: $HOME/midwork). This GUI
will create this directory if it does not exist and uses in to keep some
temporary files.
.SH ENVIRONMENT
.I helpmidas

the environment with the same performance as previous described arguments.
