-"[+NAME?pathchk - check pathnames for portability]"
-"[+DESCRIPTION?\bpathchk\b checks each \apathname\a to see if it is "
- "valid and/or portable. A \apathname\a is valid if it can be used to "
- "access or create a file without causing syntax errors. A file is "
- "portable if no truncation will result on any conforming POSIX.1 "
- "implementation.]"
-"[+?By default \bpathchk\b checks each component of each \apathname\a "
- "based on the underlying file system. A diagnostic is written to "
- "standard error for each pathname that:]"
- "{"
- "[+-?Is longer than \b$(getconf PATH_MAX)\b bytes.]"
- "[+-?Contains any component longer than \b$(getconf NAME_MAX)\b "
- "bytes.]"
- "[+-?Contains any directory component in a directory that is not "
- "searchable.]"
- "[+-?Contains any character in any component that is not valid "
- "in its containing directory.]"
- "[+-?Is empty.]"
- "}"
-"[p:components?Instead of performing length checks on the underlying "
- "file system, write a diagnostic for each pathname operand that:]"
- "{"
- "[+-?Is longer than \b$(getconf _POSIX_PATH_MAX)\b bytes.]"
- "[+-?Contains any component longer than \b$(getconf "

- "portable filename character set.]"

-"[P:path?Write a diagnostic for each pathname operand that:]"
