By default, LyX overwrites the main file when exporting from command
line but not the ancillary files. This behavior can be changed by setting
this environment variable, which relieves the need of using the \-f switch.
Allowed values are either "\fBall\fR", "\fBmain\fR" or "\fBnone\fR", with
same meaning as for the \-f switch.
