79 Placeins.sty keeps floats `in their place', preventing them from floating
80 past a "\FloatBarrier" command into another section. To use it, declare
81 "\usepackage{placeins}" and insert "\FloatBarrier" at places that floats
82 should not move past, perhaps at every "\section".
83
84 Option: [section]
85
86 A more convenient way to stop floats at section boundaries is to change
87 the definition of "\section" to include "\FloatBarrier", either at the
88 beginning, before "\@startsection", or in the `style' specification (see
89 The LaTeX Companion, section 2.2.2; or 2.3 in the 1st ed). If you specify
90 "\usepackage[section]{placeins}", then the "\section" command will be
91 redefined with "\FloatBarrier" inserted at the beginning.
92
93 Options: [above] [below]
94
95 Something you may not like is that, by default, "\FloatBarrier" is very
96 strict, and will (try to) prevent a float from appearing above the start
97 of the current section or below the start of the next section, even
98 though the float is still on the same page as its intended section.
99 Each restriction can be relaxed separately by using the "[above]" and
100 "[below]" package options: "[above]" allows floats to appear above their
101 section, if on the same page; "[below]" allows below.
102
103 NOTE! The original version of placeins.sty acted like it was loaded
104 with the option "[above]" specified.
105
106 There is a problem with LaTeX's "\suppressfloats" being out of step with
107 the page breaking (see usenet msg <yfi656pbsn0.fsf@triumf.ca> and thread)
108 which sometimes allows a float to go above a "\FloatBarrier" placed near
109 the top of a page. Maybe placeins will fix it sometime later.
110
111 Option: [verbose]
112
113 There is a package option "[verbose]" that causes many messages to be
114 written in the log file. It might be used to answer the question:
115 `How did *that* get *there*?!?'
