# SILC Toolkit Reference Manual documentation script.  This will automatically
# generate documentation from the source tree.  This will require the 
# robodoc compiled in util/robodoc and php utility installed in your system.
#
# This will tarverse the given directory and all subdirectories for the
# SILC style header files.  All header files starting with prefix `silc' 
# will be checked.  For example, silcpkcs.h.
#
# Usage: ./sildoc <type> <source directory> <destination directory> <robodoc>
#
# The <source directory> is the directory where this starts checking for
# the headers and will traverse all subdirectories.  The <destination
# directory> is the directory to where the documentation is generated.
#
