/*
CloneDate.exe, Version 0.50 BETA
Modify the LastModified date (timestamp) of the target file(s) to
match the specified source file's timestamp
Usage: CloneDate.exe sourcefile targetfiles [ /Debug ]
Where: sourcefile is the file whose timestamp is to be cloned
targetfiles are the files whose timestamp are to be modified
(single filespec, wildcards * and ? are allowed)
/Debug displays file name and timestamps before and
after modification for each matching file
Example: CloneDate.exe C:\boot.ini C:\test.log
will change C:\test.log's timestamp to match C:\boot.ini's
Notes: Target filespec may include sourcefile (sourcefile will be skipped).
Always be careful when using wildcards; they may also return matching
"short" (8.3) file names (for backwards compatibility with FAT16).
