This utility can be used to summarize disk usage of files in PNFS, 
recursively for directories, and to get the result in form of a
well-formed HTML page for viewing in web-browsers.

Usage: 

osg_dc_get_html_dump_of_fs_usage_of_pnfs_dir [options] <files or directories>

Required Arguments:
	<files or directories>       PNFS directory name. It supports 
                                     glob expansion, e.g.,
                                     '/pnfs/mit.edu/d*'
                                     Or you can let the shell expand 
                                     the wildcard.
Optional Arguments:
	-a, --all             Write counts for all files, not just for 
                              directories.
	-c, --total           Produce a grand total.
	--not-pnfs            Act on a normal (non-PNFS) filesystem.
                              Does not follow symlinks.
	-f, --number-of-files    Report number of files contained in 
                                 directories.
	--html                Output in an HTML format, with or without 
                              --not-pnfs. If using this option, please do
                              not specify other options or use globs (*).
                              E.g., (1) --html /pnfs/cmsaf.mit.edu/
                                    (2) --not-pnfs --html /home
	--html-no-files       Like --html, but print only directories, not
                              individual files. For quicker loading in 
                              web-browsers.
	-H, --human-readable  Print sizes in human readable format.
	-r, --replicas        Include replicas when determining sizes.
	-s, --summary         Display only a total for each argument.
