 * This program is intended as a utility to help software developers
 * ensure that their source file names are distinguishable on MS-DOS and
 * 14-character SYSV platforms.  To perform this task, doschk reads a
 * list of filenames and produces a report of all the conflicts that
 * would arise if the files were transferred to a MS-DOS or SYSV
 * platform.  It also reports any file names that would conflict with
 * MS-DOS device names.
 *
 * To use this program, you must feed it a list of filenames in this
 * format:
 *
 *         dir
 *         dir/file1.ext
 *         dir/file2.exe
 *         dir/dir2
 *         dir/dir2/file3.ext
 *
 * If the list does not include the directory-only lines (like dir/dir2)
 * then their names will not be checked for uniqueness, else they will
 * be.  Typical uses of this program are like these:
 *
 *         find . -print | doschk
 *         tar tf file.tar | doschk
 *
 * If this program produces no output, then all your files are MS-DOS
 * compatible.  Any output messages are designed to be self-explanatory
 * and indicate cases where the files will not transfer to MS-DOS without
 * problems.
