Mapweaver/Manual/Debug

Verbose will turn on information to be printed while program executes. Some useful information might be obtained.

-verbose 

Debug will print lots of information and should only be used in conjunction with a redirect of STDOUT.

-debug

If you want to print a map only containing multipolygons you can specify so. This is also a debug function, although a graphical one.

-multionly (draws only areas of multipolygons; for test purposes)
