Comment Code Column:
	The column in which comments on code start.

Comment Declaration Column:
	The column in which comments on declarations start.
	
Continuation Indent:
	Sets the continuation indent to be n.  Continuation lines will be indented that far from the beginning of the first line of the statement.  Parenthesized expressions have extra indentation added to indicate the nesting.

Indent case labels tabs:
	Causes case labels to be indented n tab stops to the right of the containing switch statement.  -cli0.5 causes case labels to be indented half a tab stop. (This is the only option that takes a fractional argument.)

Negative indents for comment lines:
	Controls the placement of comments which are not to the right of code.  Specifying 1 means that such comments are placed one indentation level to the left of code.  
	
Indent variable name declarations:
	Specifies the indentation, in character postions, from a declaration keyword to the following identifier.
	
Space for one indentation level:
	The number of spaces for one indentation

Maximum Line Length:
	Maximum length of an output line.   Note:   I can't figure out what they mean by this.  Indent certainly does not seem to be doing what I think it says...
	
Maximum Commented Line Length:
	Maximum length of a line containing a comment.

Tab stop width:
	Specifies the width of tab stops.
