# shell script to find all mixed case *.fd and *enc.def files
# Offers to delete them if lowercase version exists in same diretory,
# otherwise to rename them to lowercase.

# Asks for every file whether to do the action (y/n).
# Could be made  to do all files, but I don't want to be responsible for
# distributing a find script that executes rm in any but the safest fashion.

# However if you want to apply this to a large directory you will want
# to disable the questions, in that case uncomment the second line
# below, to set force=true.
