ENVIRONMENT VARIABLES
wine makes the environment variables of the shell
from which wine is started accessible to the windows/dos processes started.
So use the appropriate syntax for your shell to enter environment variables
you need.

WINEDEBUG
Turns debugging messages on or off. The syntax of the variable
is of the form [class][+/-]channel[,[class2][+/-]channel2].
class is optional and can be one of the following:
err, warn, fixme, or trace. If class is not specified,
all debugging messages for the specified channel are turned on.
Each channel will print messages about a particular component of wine.
The following character can be either + or - to switch
the specified channel on or off respectively.
If there is no class part before it, a leading + can be omitted.
Note that spaces are not allowed anywhere in the string.
Examples:
WINEDEBUG=warn+all
will turn on all warning messages
(recommended for debugging).
WINEDEBUG=warn+dll,+heap
will turn on DLL warning messages and all heap messages.
WINEDEBUG=fixme-all,warn+cursor,+relay
will turn off all FIXME messages, turn on cursor warning
messages, and turn on all relay messages (API calls).
WINEDEBUG=relay
will turn on all relay messages.
For more control on including or excluding functions
and dlls from the relay trace look into the [Debug] section
of the wine configuration file.
For more information on debugging messages,
see the Running Wine chapter of the Wine User Guide.
