GhostScript的源代码

<b><tt>pstotext</tt></b> uses Ghostscript to extract plain text from
PostScript files.  It is much better than the <b><tt>ps2ascii</tt></b>

CompuServe announced in December 1995 that the Graphics Support Forum
offers Message Section and Library 21, "Ghostscript", for technical
assistance with Ghostscript.  Ghostscript is available for downloading in
Library 21, "Ghostscript." To access the Graphics Support Forum,
<b><tt>GO GRAPHSUP</tt></b>.  This service has no connection
with Aladdin Enterprises.

<p>
Aladdin Enterprises doesn't have the resources to respond to questions from
users of the freely available versions of Ghostscript.  (Responding to
questions and bug reports is one of the benefits that
<a href="#Commercial_use">Artifex Software</a> provides to commercial users
in exchange for the licensing fee.)  If you have problems with Ghostscript
and you have access to the Internet, we suggest to post your question to
one of these Usenet newsgroups:

<dl>
<dt><b><tt><a href="news:gnu.ghostscript.bug">gnu.ghostscript.bug</a></tt></b>
<dd>if your question is about <b>GNU Ghostscript</b> (currently versions
4.03 and below).  If you have access to Internet mail, but not Usenet news,
write to <b><tt>[e-mail]</tt></b>, which is equivalent to
posting to that newsgroup.

<dt><b><tt><a href="news:comp.lang.postscript">comp.lang.postscript</a></tt></b>
<dd>if your question is about <b>Aladdin Ghostscript</b> (currently
versions above 4.03).  If you have access to Internet mail, but not Usenet
news, write to <b><tt>[e-mail]</tt></b>, which is
equivalent to posting to that newsgroup.  We hope to establish a separate
newsgroup for Aladdin Ghostscript in the future, since
<b><tt>comp.lang.postscript</tt></b> was not intended for Ghostscript
discussion <em>per se</em>.
</dl>

<p>
There are hundreds of Ghostscript user sites all over the world, and
another user will often be able to help you.  If you have trouble with a
specific device driver, look at <b><tt>devs.mak</tt></b> and
<b><tt>contrib.mak</tt></b> in the Ghostscript source directory to see in
which file the driver is defined.  If it's defined in
<b><tt>contrib.mak</tt></b>, the list of contributed drivers, please
contact the author directly.  Aladdin Enterprises can't help you with
user-maintained drivers.

<h2><a name="Reporting_bugs"></a>Reporting bugs</h2>

<p>
Aladdin Enterprises does want Ghostscript to be of high quality, so if you
have been running Ghostscript and encounter a problem, we encourage you to
post bugs to the newsgroups mentioned above.  Before doing that, however,
you should first check the "known bugs" notice at

<blockquote>
<a href="http://www.cs.wisc.edu/~ghost/aladdin/relnotes/">http://www.cs.wisc.edu/~ghost/aladdin/relnotes/</a>gs###/index.html
</blockquote>

<p>
where "###" is the unpunctuated version number of Ghostscript's latest
release.

<p>
We will consider investigating problems reported to those newsgroups, or
e-mailed directly to &lt;<a href="mailto:[e-mail]">[e-mail]</a>&gt;,
if (and only if) the report meets all the following conditions:

<ol>
<li>You are using the most recent version of Aladdin Ghostscript.

<li>You obtained Ghostscript directly from Aladdin Enterprises, or from the
<a href="#Find_Ghostscript">FTP or AFS site</a> on the Internet mentioned
above (that is, not from a bulletin board system or a commercial system
such as CompuServe).

<li>You have installed Ghostscript successfully, and used it successfully
on other input data.

<li>Your problem is reproducible, and you can provide the input data that
evokes it, either by e-mail in the problem report itself
(if data is less than 100K bytes) or by anonymous FTP or HTTP.

<li>Your problem is reproducible with Ghostscript alone, without using a
viewer such as Ghostview or GSview.  (If a problem happens only with
Ghostview, write to Tim Theisen
&lt;<a href="mailto:[e-mail]">[e-mail]</a>&gt;.
If it happens only with GSview, contact Russell Lang
&lt;<a href="mailto:[e-mail]">[e-mail]</a>&gt;.)

<li>You created the bug report by filling out the
<a href="Bug-form.htm">bug form</a> <em>completely</em>.  We really do
mean "<em>completely</em>" -- fill in every item that applies to your
situation.  To e-mail it, use your browser to save it as text, then
complete it and send the completed report.
</ol>

<p>
Bug reports that include suggested fixes are especially welcome.  As time
permits, Aladdin Enterprises may also respond to e-mail from the following
classes of users:

<ol>
<li>Beta testers who have actually given us at least one report on some
beta version supplied to them.

<li>People developing drivers for Ghostscript or applications based on it,
and that will be made freely available.

<li>People who express serious interest in
<a href="#Commercial_use">licensing Ghostscript commercially</a>.
</ol>

<p>
Aladdin Enterprises owns or has access to the following hardware and
software:

<ul>
<li> Pentium and 486 PCs with color SuperVGA displays; Epson-compatible
printer (the printer also is compatible with the IBM Proprinter); various
H-P printers.  These systems run MS-DOS 5.0 and 6.22 and Microsoft Windows
3.1 and 95 with Borland C++ 4.0 (and several older versions), Watcom C++
10.0, and Microsoft Visual C++ 4.0, and Linux with gcc

<li> SPARCstation, SunOS 4.1, cc and gcc, X11R5 and SunView; both
monochrome and color displays

<li> DECstation, Ultrix

<li> IBM RS/6000 and PowerPC, Unix (AIX 3.n)

<li> Alpha with Digital Unix
</ul>

<p>
If your problem turns out to be specific to some other hardware or
software configuration, it may take longer to track down, since we
will have to rely on other users to help.

<h1><a name="Aladdin"></a>Contacting Aladdin Enterprises</h1>

<p>
Please do not contact us if all you want is help with the freely
distributed versions of Ghostscript!  Ghostscript is free, but our time is
not.  If you call for help, we will tell you politely that we cannot answer
your question.  Ghostscript's documentation, while not of commercial
end-user quality, has been adequate for thousands of users (for many of
whom English is a foreign language), so the answer to your question is very
likely in it somewhere.

<p>
Here is our contact information:

<blockquote><address>

<h1><a name="How_to_help"></a>Things you can do to help</h1>

<p>
There are some projects that users could do that are somewhat independent
of the main body of the code, and that would help improve Ghostscript.

<ul>
<li>Make Ghostscript work with the free <b><tt>emx/gcc</tt></b> and
<b><tt>rsx</tt></b> libraries to provide an alternative DOS,
Windows 95/98/NT, and OS/2 implementation that requires no proprietary,
commercial compilers.  We think Ghostscript's existing OS/2 makefile already
includes most of what is needed.  If someone is willing to do the work, we
will be happy to include this in our list of supported platforms and to
distribute the makefiles.  If interested, please consult

<blockquote>
<a href="http://www.leo.org/pub/comp/os/os2/leo/gnu/emx+gcc/">http://www.leo.org/pub/comp/os/os2/leo/gnu/emx+gcc/</a>
</blockquote>

<p>
and then <a href="#Aladdin">contact Aladdin</a> if you want to do the work.
</ul>

<ul>
<li>We would like to provide (Adobe) PrintGear and (H-P) PPA output drivers
for Ghostscript, but the specifications for these protocols are not
published.  If you can provide them to us without violating any agreements,
please <a href="#Aladdin">contact Aladdin</a>.
</ul>
