+.SH NAME
+cline \- count line terminator characters in files
+.SH SYNOPSIS
+.B cline
+.RI [ Options ]
+.RI [ Directories... ]
+.SH DESCRIPTION
+.B cline
+counts the line terminator characters
+.RB ( \en )
+within all files in the specified directories.
+
+If no directory is specified,
+.B cline
+scans the current directory.
+.SH OPTIONS
+.TP
+.BI \-b " level"
+Set the binary file heuristics level. The default is
+.BR medium .
+Valid levels are:
+.BR ignore ,
+.BR low ,
+.BR medium ,
+and
+.BR high .
+The heuristics use the ratio of non-printable characters after seeing
+enough printable characters in the file (see
+.MR isprint 3 ).
+The higher the detection level, the
+more printable characters the algorithm wants to see before making a decision.
+
+Note that some Unicode files with a high ratio of non-printable
+characters from the perspective of
+.MR isprint 3 ,
+might be misdetected by this algorithm as binary files.
+.TP
+.B \-c
+Count non-whitespace characters instead of lines.
+.TP
+.B \-d
+Report only directory sums.
+.TP
+.BI \-D " path"
+Exclude the directory at the specified
+.IR path .
+A path can be relative or absolute but must always contain at least one path
+separator. For example, if you want to exclude the top-level
+.IR target
+directory in a project of yours, use
+.BI \-D " ./target"
+to specify a path relative to your current directory. If you just write
+.BI \-D " target"
+you would exclude
+.IR all
+directories with that name in an recursive search with the
+.BR -r
+option.
+This option may be used multiple times.
+.TP
+.BI \-D " name"
+Exclude all directories with the given
+.IR name .
+This option may be used multiple times.
+.TP
+.BI \-E " pattern"
+Exclude any line matching the regular expression
+.IR pattern .
+This option may be used multiple times.
+.TP
+.BI \-e " start end"
+Exclude lines between the regular expressions
+.I start
+and
+.IR end .
+The first and the last line are only excluded when they completely match the
+.IR start " or " end
+pattern, respectively.
+Similarly, when used with the
+.BR \-c
+option, characters within a line before
+.IR start
+matches and after
+.IR end
+matches are still counted.
+This option may be used multiple times.
+.TP
+.BR \-h ", " \-\-help
+Print help text and exit.
+.TP
+.B \-i
+Print individual sums per file extension.
+This option cannot be used together with
+.BR \-V .
+.TP
+.B \-m
+Print information about matching files only.
+.TP
+.BI \-s " suffixes"
+Only count files with these suffixes.
+Suffixes are separated by commas.
+.TP
+.BI \-S " suffixes"
+Count any file except those with these suffixes.
+Suffixes are separated by commas.
+.TP
+.BR \-r ", " \-R
+Scan subdirectories recursively.
+.TP
+.BR \-v ", " \-\-version
+Print version information.
+.TP
+.B \-V
+Turn verbose output off and print the result only.
+.SH SHORTCUTS
+.TP
+.B \-\-exclude\-cstyle\-comments
+Equivalent to:
+.BR "\-E '\es*//'" " " "\-e '\es*/\e*' '\e*/\es*'"
+.TP
+.B \-\-exclude\-blank\-lines
+Equivalent to:
+.BR "\-E '^\es*$'"
+.SH EXAMPLES
+.TP
+.B cline \-rms .c,.h \-\-exclude\-cstyle\-comments
+Recursively count matching
+.I .c
+and
+.I .h
+files, print matching files only, and exclude C-style comments.
+.TP
+.B cline \-Vc src
+Print only the total number of non-whitespace characters in
+.IR src .
+.TP
+.B cline \-rms .rs \-D ./target
+Recursively count matching Rust source files starting with the current
+directory, but skip the target directory. Print only matching files.
+.TP
+.B cline \-rb high -d -D .git
+Recursively count all non-binary files with a high binary file detection
+heuristic. Report only sums per directory and skip all directories with the
+name
+.IR .git .
