NAME

       checknr - Checks nroff files

SYNOPSIS

       checknr [-fs] [-a.x1.y1.x2.y2 ... .xn.yn] [-c.x1.x2.x3 ... .xn] [file...]

       The  checknr command checks a list of nroff input files for certain kinds of errors involving mismatched opening and closing delimiters and
       unknown commands.

OPTIONS

       Adds pairs of macros to the list.  This option must be followed by groups of six characters, each group defining a pair of macros. The  six
       characters are a period, the first macro name, another period, and the second macro name. For example, to define a pair and -a.BS.ES.  (You
       cannot use the -a option to define a 1-character macro name.)  Defines otherwise undefined commands.  Causes  checknr  to  ignore  f  font
       changes.  Causes checknr to ignore s size changes.

DESCRIPTION

       If  no  files  are specified, checknr checks the standard input.  Delimiters checked are as follows: Font changes using fx ...	fP.  Size
       changes using sx ...  s0.  Macros that come in open/close forms (for example, the

       and macros), which must always come in pairs.

       The checknr command can handle both the ms and me macro packages.

       The checknr command is intended to be used on documents that are prepared with checknr in mind, much the same as lint. It expects a certain
       document writing style for f and s commands, in that each fx must be terminated with fP and each sx must be terminated with s0. While
       it will work to go directly into the next font or explicitly specify the original font or point size, and many existing documents  actually
       do this, such a practice produces error messages from checknr.

       The checknr command does not recognize certain reasonable constructs, such as conditionals.
