+"[+NAME?paste - merge lines of files]"
+"[+DESCRIPTION?\bpaste\b concatenates the corresponding lines of a "
+ "given input file and writes the resulting lines to standard "
+ "output. By default \bpaste\b replaces the newline character of "
+ "every line other than the last input file with the TAB character.]"
+"[+?Unless the \b-s\b option is specified, if an end-of-file is encountered "
+ "on one or more input files, but not all input files, \bpaste\b "
+ "behaves as if empty lines were read from the file(s) on which "
+ "end-of-file was detected.]"
+"[+?Unless the \b-s\b option is specified, \bpaste\b is limited by "
+ "the underlying operating system on how many \afile\a operands "
+ "can be specified.]"
+"[+?If no \afile\a operands are given or if the \afile\a is \b-\b, \bpaste\b "
+ "reads from standard input. The start of the file is defined as the "
+ "current offset.]"
+
+"[s:serial?Paste the lines of one file at a time rather than one line "
+ "from each file. In this case if the \b-d\b option is "
+ "specified the delimiter will be reset to the first in the "
+ "list at the beginning of each file.]"
+"[d:delimiters]:[list?\alist\a specifies a list of delimiters. These "
+ "delimiters are used circularly instead of TAB to replace "
+ "the newline character of the input lines. Unless the \b-s\b "
+ "option is specified, the delimiter will be reset to the first "
+ "element of \alist\a each time a line is processed from each file. "
+ "The delimiter characters corresponding to \alist\a will be found "
+ "by treating \alist\a as an ANSI-C string, except that the \b\\0\b "
+ "sequence will insert the empty string instead of the null character.]"
+"\n"
+"\n[file ...]\n"
+"\n"
+"[+EXIT STATUS?]{"
+ "[+0?All files processed successfully.]"
+ "[+>0?An error occurred.]"
