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

74 For example, to define a pair .BS and .ES, use
77 Define commands which would otherwise be complained about
91 Delimiters checked are:
94 Font changes using \efx ... \efP.
96 Size changes using \esx ... \es0.
98 Macros that come in open ... close forms, for example,
99 the .TS and .TE macros which must always come in pairs.
