47 utility checks a list of
51 input files for certain kinds of errors
52 involving mismatched opening and closing delimiters
54 If no files are specified,
56 checks the standard input.
58 The following options are available:
59 .Bl -tag -width indent
61 Add additional pairs of macros to the list of known macros.
62 This must be followed by groups of six characters, each group defining
64 The six characters are

86 Delimiters checked are:
89 Font changes using \efx ...\& \efP.
91 Size changes using \esx ...\& \es0.
93 Macros that come in open ...\& close forms, for example,
94 the .TS and .TE macros which must always come in pairs.
