summarize(sdone = [], ldone = [], width = 1, max = width - 1, indent = "")
public
Produces the summary text. Each line of the summary is yielded to the block
(without newline).
sdone |
Already summarized short style options keyed hash.
|
ldone |
Already summarized long style options keyed hash.
|
width |
Width of left side (option part). In other words, the right
|
side (description part) starts after +width+ columns.
max |
Maximum width of left side -> the options are filled within
|
+max+ columns.
indent |
Prefix string indents all summarized lines.
