32 /* Fixed labels are printed flushright, manual labels flushleft.
33 * MARGIN_MANUAL and MARGIN_FIRST_DYNAMIC are *only* for LABEL_MANUAL,
34 * MARGIN_DYNAMIC and MARGIN_STATIC are *not* for LABEL_MANUAL.
35 * This seems a funny restriction, but I think other combinations are
36 * not needed, so I will not change it yet.
37 * Correction: MARGIN_FIRST_DYNAMIC also usable with LABEL_STATIC.
41 /* There is a parindent and a parskip. Which one is used depends on the
42 * paragraph_separation-flag of the text-object.
43 * BUT: parindent is only thrown away, if a parskip is defined! So if you
44 * want a space between the paragraphs and a parindent at the same time,
45 * you should set parskip to zero and use topsep, parsep and bottomsep.
47 * The standard layout is an exception: its parindent is only set, if the
48 * previous paragraph is standard too. Well, this is LateX and it is good!
