doschk - check filenames for DOS (and SYSV) compatibilityThis program is intended as a utility to help software developersensure that their source file names are distinguishable on MS-DOS and14-character SYSV platforms.  To perform this task, doschk reads alist of filenames and produces a report of all the conflicts thatwould arise if the files were transferred to a MS-DOS or SYSVplatform.To use this program, you must feed it a list of filenames in thisformat:	dir	dir/file1.ext	dir/file2.exe	dir/dir2	dir/dir2/file3.extIf the list does not include the directory-only lines (like dir/dir2)then their names will not be checked for uniqueness, else they willbe.  Typical uses of this program are like these:	find . -print | doschk	tar tf file.tar | doschkIf this program produces no output, then all your files are MS-DOScompatible.  Any output messages are designed to be self-explanatoryand indicate cases where the files will not transfer to MS-DOS withoutproblems.Please report bugs to bug-gnu-utils@prep.ai.mit.edu.
