+$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.
