46 utility checks a list of
50 input files for certain kinds of errors
51 involving mismatched opening and closing delimiters
53 If no files are specified,
55 checks the standard input.
57 The following options are available:
58 .Bl -tag -width indent
60 Add additional pairs of macros to the list of known macros.
61 This must be followed by groups of six characters, each group defining
63 The six characters are
67 and the second macro name.
68 For example, to define a pair .BS and .ES, use
71 Define commands which would otherwise be complained about
85 Delimiters checked are:
88 Font changes using \efx ... \efP.
90 Size changes using \esx ... \es0.
92 Macros that come in open ... close forms, for example,
93 the .TS and .TE macros which must always come in pairs.
