Section 5.3.5.2.1.1. Copying

In its simplest application, the program copies a CIF from the standard input channel to standard output. The copy is not verbatim (standard utilities of the computer operating system should be used for that purpose), but the output CIF differs from the input only in the following respects: some comments are deleted; lines in the input longer than 80 characters are wrapped to 80 characters or less; white space between tokens may be altered, especially in an attempt to align entries in looped lists in a cosmetically pleasing manner. While none of these changes should affect robust CIF-parsing applications, they are nevertheless useful in imposing a uniform style of presentation for browsing in a text editor or other human-readable framework.
