#   Purpose: for directories that have subdirectories (names of which are
#            provided in the file <subdir>/'docdirs') creates a new AllMains.tex
#            file and in each subdirectory named in 'docdirs' adds a link
#            to ./html_wrapper.
#
#   Usage:   clean_start [d1 d2 ...]



# clean the listed directories, or, if this directory contains wrapper.tex file,
# clean this directory, or if no wrapper.tex but a docdirs, clean the 
# directories listed in docdirs.  Otherwise, clean nothing.
