#
# Typical usage:
# dohtml -r docs/*
#  - put all files and directories in docs into /usr/share/doc/${PF}/html
# dohtml foo.html
#  - put foo.html into /usr/share/doc/${PF}/html
#
#
# Detailed usage:
# dohtml <list-of-files> 
#  - will install the files in the list of files (space-separated list) into 
#    /usr/share/doc/${PF}/html, provided the file ends in .html, .png, .jpg 
#     or .css
# dohtml -r <list-of-files-and-directories>
#  - will do as 'dohtml', but recurse into all directories, as long as the 
#    directory name is not CVS
# dohtml -A jpe,java [-r] <list-of-files[-and-directories]>
#  - will do as 'dohtml' but add .jpe,.java (default filter list is
#    added to your list)
# dohtml -a png,gif,html,htm [-r] <list-of-files[-and-directories]>
#  - will do as 'dohtml' but filter on .png,.gif,.html,.htm (default filter 
#    list is ignored)
# dohtml -x CVS,SCCS,RCS -r <list-of-files-and-directories>
#  - will do as 'dohtml -r', but ignore directories named CVS, SCCS, RCS
#
