# If a SDFDirector has no iterations parameter, then insert one
# and set it to 0.

# Note that now that iterations is set to AUTO by default in SDFDirector,
# this script is probably not necessary.

# Usage: fix-files [-n] [-d] 

# Typical usage


# 1. Generate a file that contains the names of the .xml files
#   cd $PTII
#   adm/bin/ptIItxtfiles | egrep '.xml$' >& /tmp/xmlFiles
#
# 2. Generate a file that contains the names of the .xml files that have
#    SDFDirector or its derived classes.
#   cat /tmp/xmlFiles | xargs egrep 'SDFDirector"|DTDirector"|HDFDirector"|PthalesDirector"' | awk -F : '{print $1}' | sort | uniq > /tmp/sdfFiles
#
#
# 3. Review /tmp/sdfFiles by hand for .xml files that are used to
#    define actors in the library, for example
#   doc/findbugsOut.xml
#   ptolemy/configs/*.xml
#
# 4. Run the script without updating the files.
#   $PTII/ptolemy/domains/sdf/kernel/fixSDFIterations -n `cat /tmp/sdfFiles`
#
# 5. Run the script with updating the files:
#   $PTII/ptolemy/domains/sdf/kernel/fixSDFIterations `cat /tmp/sdfFiles`
