 the -o or --output option simply tells ASCIISite what to name the output file.
 
+the --exclude flag allows you to specify a list of glob patterns. Any file matching these glob patterns will not be copied to the output.
+This is helpful for any files that are needed for the compilation of the asciidoc files, but do not need to be in the final site.
+The main use case I am aware of is files that are put into an asciidoc document via an include statement.

 the -z or --compress flag tells ASCIISite to put the final product in a compressed tar.gz file as its output. 
 This is especially useful if you are running ASCIISite on your personal computer, and will be uploading the tar.gz file to your server.

+If, say, the include directory is a directory needed for the asciidoc compilation,

+````
+ASCIIsite.py --exclude 'include*' -o output test
