#The following script file is useful to convert old theory files into a
#style consistent with new naming conventions. Now, the names of the
#files must be the same as the names of the theories they define (with
#a ".thy" suffix) and corresponding ML files must also be renamed.
#
#To make this renaming easier, the following perl script can be used.
#It traverses the given directory recursively.  For each file of the
#form abc.thy, this script does the following steps:
#
#1. Reads the file and grabs the first identifier, say Abc (skipping comments
#   (*...*) and white space).
#2. Outputs the commands needed to rename the file abc.thy to Abc.thy,
#   including the appropriate CVS commands.
#3. If abc.ML also exists, it outputs appropriate commands to rename it
#   to Abc.ML.
#
#These commands can be put into a file, which can then be executed.
#If you are not using cvs, use "grep" to extract just the "mv" commands.
