wget -nH removes the "hostname" directories. In other words, it skips over the primary domain name. For instance, wget would skip the www.w3.org binder in the previous example and start with the History directory instead.
wget --cut-dirs=# skips the specified number of directories down the URL before starting to download files. For case, -nH --cut-dirs=1 would change the specified path of "ftp.xemacs.org/pub/xemacs/" into simply "/xemacs/" and reduce the number of empty parent directories in the local download.
wget -R alphabetize.html/wget --refuse alphabetize.html will skip any files matching the specified file name. In this case, it will exclude all the index files. The asterisk (*) is a wildcard, such as "*.png". This would skip all files with the PNG extension.
wget -i file specifies target URLs from an input file. This input file must be in HTML format, or you'll need to use the --force-html flag to parse the HTML.
