+Another complication is the fact that some glyphs which represent bracket
+pieces in original troff can be used for other mathematical symbols also,
+for example `lf' and `rf' which provide the `floor' operator.
+.
+Other devices (most notably for DVI output) don't unify such glyphs.
+.
+For this reason, the four glyphs `lf', `rf', `lc', and `rc' are not
+unified with similarly looking bracket pieces.

+.P
+These glyphs are intended for technical use, not for real Greek; normally,
+the uppercase letters have upright shape, and the lowercase ones are
+slanted.
+.
+There is a problem with the mapping of letter phi to Unicode.
+.
+Prior to Unicode version\ 3.0, the difference between U+03C6, GREEK
+SMALL LETTER PHI, and U+03D5, GREEK PHI SYMBOL, was not clearly described;
+only the glyph shapes in the Unicode book could be used as a reference.
 .
+Starting with Unicode\ 3.0, the reference glyphs have been exchanged and
+described verbally also: In mathematical context, U+03D5 is the stroked
+variant and U+03C5 the curly glyph.
+.
+Unfortunately, most font vendors didn't update their fonts to
+this (incompatible) change in Unicode.
+.
+At the time of this writing (February 2003), it is not clear yet whether
+the Adobe Glyph Names `phi' and `phi1' also change its meaning if used for
+mathematics, thus compatibility problems are likely to happen \(en being
+conservative, groff currently assumes that `phi' in a PostScript symbol
+font is the stroked version.
 .P
+In groff, symbol `\f(CW\e[*f]\fP' always denotes the stroked version of
+phi, and `\f(CW\e[+f]\fP' the curly variant.

+.B papersize
+This macro file is already loaded at start-up by
+.B @g@troff
+so it isn't necessary to call it explicitly.
+.
+It provides an interface to set the paper size on the command line with
+the option \f[B]\%\-dpaper=\f[]\f[I]size\f[].
+.
+Possible values for
+.I size
+are the same as the predefined
+.B papersize
+values in the DESC file (only lowercase; see
+.BR groff_font (@MAN5EXT@)
+for more) except
+.BR a7 - d7 .
+.
+An appended
+.B l
+(ell) character denotes landscape orientation.
+.
+Examples:
+.BR a4 ,
+.BR c3l ,
+.BR letterl .
+.
+.IP
+Most output drivers need additional command line switches
+.B \-p
+and
+.B \-l
+to override the default paper length and orientation as set in the driver
+specific DESC file.
+.
+For example, use the following for PS output on A4 paper in landscape
+orientation:
+.
+.IP
+.Shell_cmd "groff \-Tps \-dpaper=a4l \-P\-pa4 \-P\-l \-ms foo.ms > foo.ps"

+.B pspic
+A single macro is provided in this file,
+.BR PSPIC ,

+.
+It makes only sense for output devices which support inclusion of PS
+images:
+.BR \-Tps ,
+.BR \-Tdvi ,
+and
+.BR \-Thtml ;
+the file is then loaded automatically.

+.
+The

+and

+arguments may have scaling indicators attached;

+.
+This macro will scale the graphic uniformly
+in the x and y\~directions so that it is no more than
+.I width
+wide
+and
+.I height
+high.
+.
+By default, the graphic will be horizontally centered.
+.
+The
+.BI \-L
+and

+options cause the graphic to be left-aligned and right-aligned,
