TIDY version 7.01 is a minor adaptation of version 7.

A minor change is that lines with ! in column 1 are treated as comments.
Some defaults have been changed to reflect a transition to F90 coding
style. The default *ENDO option changes comments to start with a !.

Another change is the invocation of TIDY and opening of files. On an
MS-DOS system, TIDY 7.01 is run by the command
                     tidy fname.ext
If an extension has been specified, then the source is assumed to be in
'fname.ext' where 'ext' may be blank. If there there is no '.ext' part,
then TIDY 7.01 looks for the source first in 'fname.for' and then in
'fname.f'. If none of these is found, then the program terminates. If the
source file is located, then the 'listing' file is named 'fname.lis' and
the 'punch' file is named 'fname.tid'.

TIDY 7.01 looks for a control file named 'tidy.ini' in the current
directory. If it is not found, then it is assumed that there is no control
file.
