+$PRODUCES test.c
+
+$BUILTIN test
+$FUNCTION test_builtin
+$SHORT_DOC test [expr]
+Evaluate conditional expression.
+
+Exits with a status of 0 (true) or 1 (false) depending on
+the evaluation of EXPR. Expressions may be unary or binary. Unary
+expressions are often used to examine the status of a file. There
+are string operators and numeric comparison operators as well.
+
+The behavior of test depends on the number of arguments. Read the
+bash manual page for the complete specification.
+
+File operators:
+
+ -a FILE True if file exists.
+ -b FILE True if file is block special.
+ -c FILE True if file is character special.
+ -d FILE True if file is a directory.
+ -e FILE True if file exists.
+ -f FILE True if file exists and is a regular file.
+ -g FILE True if file is set-group-id.
+ -h FILE True if file is a symbolic link.
+ -L FILE True if file is a symbolic link.
+ -k FILE True if file has its `sticky' bit set.
+ -p FILE True if file is a named pipe.
+ -r FILE True if file is readable by you.
+ -s FILE True if file exists and is not empty.
+ -S FILE True if file is a socket.
+ -t FD True if FD is opened on a terminal.
+ -u FILE True if the file is set-user-id.
+ -w FILE True if the file is writable by you.
+ -x FILE True if the file is executable by you.
+ -O FILE True if the file is effectively owned by you.
+ -G FILE True if the file is effectively owned by your group.
+ -N FILE True if the file has been modified since it was last read.
+
+ FILE1 -nt FILE2 True if file1 is newer than file2 (according to
+ modification date).
+
+ FILE1 -ot FILE2 True if file1 is older than file2.
+
+ FILE1 -ef FILE2 True if file1 is a hard link to file2.
+
+String operators:
+
+ -z STRING True if string is empty.
+
+ -n STRING
+ STRING True if string is not empty.
+
+ STRING1 = STRING2
+ True if the strings are equal.
+ STRING1 != STRING2
+ True if the strings are not equal.
+ STRING1 < STRING2
+ True if STRING1 sorts before STRING2 lexicographically.
+ STRING1 > STRING2
+ True if STRING1 sorts after STRING2 lexicographically.
+
+Other operators:
+
+ -o OPTION True if the shell option OPTION is enabled.
+ -v VAR True if the shell variable VAR is set.
+ -R VAR True if the shell variable VAR is set and is a name
+ reference.
+ ! EXPR True if expr is false.
+ EXPR1 -a EXPR2 True if both expr1 AND expr2 are true.
+ EXPR1 -o EXPR2 True if either expr1 OR expr2 is true.
+
+ arg1 OP arg2 Arithmetic tests. OP is one of -eq, -ne,
+ -lt, -le, -gt, or -ge.
+
+Arithmetic binary operators return true if ARG1 is equal, not-equal,
+less-than, less-than-or-equal, greater-than, or greater-than-or-equal
+than ARG2.
+
+Exit Status:
+Returns success if EXPR evaluates to true; fails if EXPR evaluates to
+false or an invalid argument is given.
+$END
+
+$BUILTIN [
+$DOCNAME test_bracket
+$FUNCTION test_builtin
+$SHORT_DOC [ arg... ]
+Evaluate conditional expression.
+
+This is a synonym for the "test" builtin, but the last argument must
+be a literal `]', to match the opening `['.
