-.TH STR 1
-
-.SH NAME
-
-str \(en test the character types of string arguments
-
-.SH SYNOPSIS
-
-str
-.RB [ type ]
-.RB [ string... ]
-
-.SH DESCRIPTION
-
-Str tests each character in an arbitrary quantity of string arguments against
-the function of the same name within ctype(3).
-
-.SH DIAGNOSTICS
-
-Str exits successfully if all tests pass and unsuccessfully if a test failed.
-.PP
-Str will exit unsuccessfully if a string is empty, as none of its contents
-passed the test.
-.PP
-Str will print a message to standard error and exit unsuccessfully if used
-improperly.
-
-.SH DEPRECATED FEATURES
-
-Str used to have an "isvalue" type as an extension to ctype(3). This was
-removed in favor of using strcmp(1) to compare strings against the empty string
-('').
-
-.SH BUGS
-
-There's no way of knowing which argument failed the test without re-testing
-arguments individually.
-.PP
-If a character in a string isn't valid ASCII str will exit unsuccessfully.
