hyphenation patterns in UTF-8 format, whereas older systems require
hyphenation patterns in the 8-bit encoding of the font in use (such encodings
are codified in the LaTeX scheme with names like OT1, T2A, TS1, OML, LY1,
etc).  The present package offers a collection of conversions of existing
patterns to UTF-8 format, together with converters for use with 8-bit fonts in
older systems.  Since hyphenation patterns for Knuthian-style TeX systems are
only read at iniTeX time, it is hoped that the UTF-8 patterns, with their
converters, will completely supplant the older patterns.")

    (description
     "The EC fonts are European Computer Modern Fonts, supporting the complete
LaTeX T1 encoding defined at the 1990 TUG conference hold at Cork/Ireland.
These fonts are intended to be stable with no changes being made to the tfm
files.  The set also contains a Text Companion Symbol font, called @code{tc},
featuring many useful characters needed in text typesetting, for example
oldstyle digits, currency symbols (including the newly created Euro symbol),
the permille sign, copyright, trade mark and servicemark as well as a copyleft
sign, and many others.  Recent releases of LaTeX2e support the EC fonts.  The
EC fonts supersede the preliminary version released as the DC fonts.  The
fonts are available in (traced) Adobe Type 1 format, as part of the
@code{cm-super} bundle.  The other Computer Modern-style T1-encoded Type 1
set, Latin Modern, is not actually a direct development of the EC set, and
differs from the EC in a number of particulars.")

    (synopsis "Arbitrary size font selection in LaTeX")
    (description
     "LaTeX, by default, restricts the sizes at which you can use its default
computer modern fonts, to a fixed set of discrete sizes (effectively, a set
specified by Knuth).  The @code{type1cm} package removes this restriction;
this is particularly useful when using scalable versions of the CM
fonts (Bakoma, or the versions from BSR/Y&Y, or True Type versions from Kinch,
PCTeX, etc.).  In fact, since modern distributions will automatically generate
any bitmap font you might need, @code{type1cm} has wider application than just
those using scalable versions of the fonts.  Note that the LaTeX distribution
now contains a package @code{fix-cm},f which performs the task of
@code{type1cm}, as well as doing the same job for T1- and TS1-encoded
@code{ec} fonts.")

offered through the latex-cyrillic and t2 bundles, and the package itself
offers support for other (more traditional) encodings.  The fonts, in the
standard T2* and X2 encodings are available in Adobe Type 1 format, in the

OT2 encoded fonts, CM bright shaped fonts and Concrete shaped fonts.")

into a globally available box, or into a box specified by the user.  The
global box may then be used in a variety of situations (for example, providing
a replica of the @code{boxedverbatim} environment itself).  A valuable use is
in places where the standard @code{verbatim} environment (which is based on a
@code{trivlist}) may not appear.")

    (description
     "Examplep provides sophisticated features for typesetting verbatim source
code listings, including the display of the source code and its compiled LaTeX
or METAPOST output side-by-side, with automatic width detection and enabled
page breaks (in the source), without the need for specifying the source twice.
Special care is taken that section, page and footnote numbers do not interfere
with the main document.  For typesetting short verbatim phrases, a replacement
for the @code{\\verb} command is also provided in the package, which can be
used inside tables and moving arguments such as footnotes and section
titles.")
