+             One particular "gotcha" is that mimeTeX bindings

+             mimeTeX correctly interprets <b>\frac12</b> as well as
+             <b>\frac1{x^2}</b>, etc, the legal LaTeX expression
+             <b>x^\frac12</b> must be written <b>x^{\frac12}</b>.
+             Otherwise, mimeTeX interprets it as <b>{x^\frac}12</b>, i.e.,
+             the same way <b>x^\alpha12</b> would be interpreted, which is
+             nonsense for <b>\frac</b>.  The same "gotcha" also applies to
+             other combinations of commands, e.g., you must write
+             <b>\sqrt{\frac\alpha\beta}</b>, or
+             <b>\frac\alpha{\sqrt\beta}</b>, etc.

+             any potential usefulness for you. --> </li>
+        <li> And there are various additional syntactic and cosmetic
+             differences between LaTeX and mimeTeX.  For example,
+             bounding boxes for mimeTeX's character bitmaps don't
+             accommodate italic corrections.  Therefore, an expression
+             like <b>\int\nolimits_a^b</b> renders
+             <a href="#preview"><img id="gotcha1" onclick="eqntext('gotcha1')"
+             src="../cgi-bin/mimetex.cgi?

+             alt="" border=0 align=middle></a><b>.</b>
+             To render the latter image you have to write the somewhat
+             cumbersome expression <b>{\smashmargin2{\int\nolimits_a}^b}</b>

+             that's imagined to be at the end of your expression. </li>
+        <li> Likewise, an unmatched &nbsp; <b>\left(</b>, &nbsp;
+             or <b>\left\{</b> &nbsp; or <b>\left\</b><i>anything</i>, &nbsp;
+             is matched by mimeTeX with a "phantom" &nbsp; <b>\right.</b>
+             &nbsp; at the end of your expression. </li>
+        <li> On the other hand, an unmatched right brace &nbsp; <b>}</b>

+             target="_top">abbreviation</a> for <b>\</b>rightarrow
+             followed by <b>\</b><i>anything</i>.  For example, &nbsp;

+ <p> <b>Please note:</b> If you're writing your own plugin for mimeTeX,
+     please don't write php code using <b>system(&nbsp;)</b>, or any other

+     &nbsp; <b>-DCACHEPATH=\&quot;<i>path/</i>\&quot;</b> &nbsp;
+     <a href="#options">compile&nbsp;option</a> instead.
+     <b>system(&nbsp;)</b> raises security
+     issues, either real ones if used carelessly, or just in the minds of
+     system administrators.  Either way, I've received many emails from
+     people unable to use mimeTeX because of unnecessary <b>system(&nbsp;)</b>
+     calls prohibited by security-conscious sysadmins.  MimeTeX itself poses
+     minimal risk when used as illustrated above, but you're responsible
+     for any plugin/wrapper script you write around it. </p>

+ <p> An image like
+     <a href="#preview"><img id="imageAV1" onclick="eqntext('imageAV1')"
+     src="../cgi-bin/mimetex.cgi?
+     \normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt"
+     alt="" border=0 align=middle></a>
+     doesn't look as good as the same image
+     <a href="#preview"><img id="imageAV2" onclick="eqntext('imageAV2')"
+     src="../cgi-bin/mimetex.cgi?
+     \normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt"
+     alt="" border=0 style="Vertical-Align:-26px"></a>
+     that's vertically aligned with your surrounding text.
+     Along with several standard
+     <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html">
+     HTTP&nbsp;header&nbsp;fields</a>, mimeTeX also emits a special
+     &nbsp; <b>Vertical-Align:&nbsp;&#150;<i>nn</i></b> &nbsp;
+     header, where <b>&#150;<i>nn</i></b> is the number of pixels
+     (usually negative as illustrated) needed for a
+     &nbsp; <b>style="Vertical-Align:&nbsp;&#150;<i>nn</i>&nbsp;px"</b>
+     &nbsp; attribute in the <b>&lt;img&gt;</b>&nbsp;tag used to
+     render your expression. This Vertical-Align:&nbsp;header
+     is obtained by placing the directive &nbsp;<b>\depth</b>&nbsp;
+     anywhere in your expression. </p>
+ <p> But mimeTeX's special Vertical-Align: header
+     is unrecognized and ignored by your browser.  You have to get the
+     header, interpret it, and write the corresponding &lt;img&gt; tag.
+     The only feasible way to do all this is using a scripting language,
+     as illustrated by the following, rather naive, php code </p>
+     <pre class="medium" style="margin-top:.5em;margin-bottom:.5em"
+ >   &lt;?php
+    $mimetexurl = "http://www.<i>yourdomain</i>.com/cgi-bin/mimetex.cgi?";
+    function verticalalign( $expression ) {
+       global $mimetexurl;
+       // note: curl_init() stops at the first whitespace char in $url argument
+       $expression = ereg_replace(" ","~",$expression); // so remove whitespace
+       $url     = $mimetexurl . "\depth~" . $expression;
+       $valign  = "0";
+       $ch      = curl_init( $url );
+       curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
+       curl_setopt( $ch, CURLOPT_HEADER, true );
+       $gif     = curl_exec( $ch );
+       $errno   = curl_errno( $ch );
+       curl_close( $ch );
+       if ( $errno == 0 ) {
+         $fields = explode("Vertical-Align:",$gif);
+         $vfield = trim($fields[1]);
+         $fldlen = strspn($vfield,"+-0123456789");
+         $valign = substr($vfield,0,$fldlen); }
+       return $valign;
+       }
+    function mimetextag( $expression ) {
+       global $mimetexurl;
+       $valign = verticalalign($expression);
+       $url    = $mimetexurl . "\depth~" . $expression;
+       echo ' &lt;img src="',$url,'" ';
+       echo ' style="Vertical-Align:',$valign,'px" ';
+       echo ' alt="" border=0&gt;', "\n";
+       }
+    ?&gt;</pre>
+ <p> Now you can write &nbsp;
+     &lt;?php&nbsp;mimetextag('\frac12\left(a^2+b^2\right)');&nbsp;?&gt;
+     wherever you want to see
+     <a href="#preview"><img id="imageAV5" onclick="eqntext('imageAV5')"
+     src="../cgi-bin/mimetex.cgi?
+     \normalsize\frac12\left(a^2+b^2\right)"
+     alt="" border=0 style="Vertical-Align:-7px"></a>
+     correctly aligned. Note that the php code automatically
+     prepends &nbsp;<b>\depth</b>&nbsp; to your expression for you.
+     <!-- Besides making you escape backslashes
+     (each&nbsp;&#092;&nbsp;must be written&nbsp;&#092;&#092;), -->
+     (Also note that this code calls mimeTeX twice to render each
+     expression, once to get the Vertical-Align: header and build
+     an &lt;img&gt; tag, and then again to render that tag.
+     If you're a good php programmer and write better code,
+     please email me a copy.) </p>
+ <p> If you're using mimeTeX's
+     &nbsp; <b>-DCACHEPATH=\&quot;<i>path</i>/\&quot;</b> &nbsp;
+     <a href="#options">compile&nbsp;option</a>, you can request
+     that all images be cached with Vertical-Align:&nbsp;headers,
+     whether or not they contain the \depth directive. Prefix your
+     <b><i>path</i>/</b> with a leading&nbsp;<b>&#037;</b> and write &nbsp;
+     <b>-DCACHEPATH=\&quot;&#037;<i>path</i>/\&quot;</b> &nbsp; instead.
+     That leading&nbsp;<b>&#037;</b> won't become part of your cache
+     directory's <b><i>path</i>/</b>, but it will signal mimeTeX
+     to cache headers along with each image. (In this case,
+     the directive &nbsp;<b>\nodepth</b>&nbsp; suppresses
+     mimeTeX's header caching for that image.)
+     <!-- Otherwise, the Vertical-Align: information is lost,
+     and attempts to align cached images will fail. --> </p>

+           Explanation: mimeTeX writes gif bytes directly to stdout, as usual
+         for cgi's.  But Windows treats stdout as a character stream,
+         interpreting any hex 0A byte as an &lt;lf&gt;, and automatically
+         preceding it with a spurious hex 0D &nbsp; &lt;cr&gt;  byte.  The
+         -DWINDOWS switch compiles in a non-portable, Windows-specific
+         _setmode() call that sets stdout to binary mode. </li>
+         <li> If you're compiling for Windows and would prefer
+         to install mimeTeX as a Win32 DLL, see the
+         <a href="http://www.codeproject.com/dotnet/Eq2Img.asp">

+         from another, you may instead see messages like <br>
+         <img src="../cgi-bin/mimetex.cgi?\message{3}"
+         alt="" align="middle" border=0> <br>
+         In this case, compile mimetex.cgi with the -DNOREFCHECK switch,
+         <i>e.g.</i>,<br>
+              <nobr> &nbsp; &nbsp; &nbsp; &nbsp; <b>cc -DAA -DNOREFCHECK

-         align=middle> &nbsp; in the upper-left corner of your window. </li>
-    <li> After the preceding test succeeds, you can optionally

+  <p class="continue"> mimeTeX can evaluate arithmetic expressions,

+      <a href="#newcommands">\newcommand's</a> discussed above.
+      Expressions can be built up from the following elements </p>
+      <ul>
+        <li> digits &nbsp; <b>0</b>-<b>9</b>
+          &nbsp; and numbers composed of uninterrupted (no whitespace)
+          sequences of digits, </li>
+        <li> binary operators &nbsp;
+          <b>+</b>,&nbsp;<b>-</b>,&nbsp;<b>*</b>,&nbsp;<b>/</b>,&nbsp;<b>%</b>
+          &nbsp; (<b>+</b>&nbsp;and&nbsp;<b>-</b> can be unary, preceding
+          the first number in an expression, and&nbsp;<b>%</b>&nbsp;is
+          the modulo operator), </li>
+        <li> balanced &nbsp; <b>(</b>&nbsp;...&nbsp;<b>)</b>
+          &nbsp; parentheses nested to any level (see below), </li>
+        <li> whitespace anywhere
+          (except between digits comprising a number), </li>
+        <li> One additional construction interpreted by <b>\eval{&nbsp;}</b>
+          is similar to (but not identical to) the
+          <a href="http://wikipedia.org/wiki/Conditional_(programming)#As_a_ternary_operator"
+          target="_top">?:&nbsp;conditional</a>, as follows.
+          The expression <b>(i?v0:v1:v2:<i>etc</i>)</b>, usually
+          parenthesized as illustrated, evaluates to <b>v0</b>
+          if <b>i</b> evaluates to <b>0</b>, or evaluates to <b>v1</b>
+          if <b>i</b> evaluates to <b>1</b>, etc. If <b>i&nbsp;&lt;&nbsp;0</b>
+          then <b>v0</b> is used, and if <b>i</b> is too large, the last
+          <b>v</b> is used. All components, <b>i</b> and all <b>v</b>'s,
+          can themselves be expressions, even another
+          <b>(i?v0:v1:v2:<i>etc</i>)</b>, which in this case must be
+          parenthesized. The only situation where parentheses aren't
+          required is when <b>i?v0:v1:v2:<i>etc</i></b> comprises
+          your entire expression.
+          For example, <br> <nobr>&nbsp; &nbsp; &nbsp;
+            <b>\eval{1+2?10:11:12:13:14:15}</b> renders
+           <a href="#preview"><img id="eval1" onclick="eqntext('eval1')"

+            the built-in variables<br>
+            &nbsp; &nbsp; &nbsp; <b>fs</b> for current fontsize and<br>
+            &nbsp; &nbsp; &nbsp; <b>unitlength</b> for unitlength<br>
+          which provide the capability for useful constructions,
+          as follows... </li>
+      </ul>
+  <p> All optional <b>[</b>&nbsp;<b>]</b> and mandatory
+      <b>{</b>&nbsp;<b>}</b> numeric arguments for &nbsp;
+      <a href="#rule">\rule[lift]{width}{height}</a>, &nbsp;
+      <a href="#compose">\compose[offset]{&nbsp;}{&nbsp;}</a>, &nbsp;

+      <a href="#raiserotate">\rotatebox{angle}{&nbsp;}</a>, &nbsp; and &nbsp;
+      <a href="#arrows">\longarrow[width]</a> &nbsp;
+      can be expressions as described above, rather than just
+      numeric constants. By using the <b>fs</b> variable, you can
+      construct <a href="#newcommands">\newcommand</a>
+      expressions that properly scale with font&nbsp;size.
+      For example, the <b>\mapsto</b> symbol is not explicitly provided
+      in any mimeTeX font, but is instead constructed by the
+      embedded <a href="#newcommands">\newcommand</a><br>
+        <nobr>&nbsp; &nbsp; &nbsp;<b>
+        { "\\mapsto", NULL, "{\\rule[fs/2]{1}{5+fs}\\hspace{-99}\\to}" },</b>
+        </nobr><br>
+      where \rule's [lift]=fs/2 and {height}=5+fs are scaled by
+      font&nbsp;size to render symbols<br>
+      &nbsp;
+       <a href="#preview"><img id="eval2" onclick="eqntext('eval2')"
+       src="../cgi-bin/mimetex.cgi?\small\text\begin{array}{rrl}

+       \backslash large & fs=\large\eval{fs} & \large\mapsto \\
+       etc. & &
+       \end{array}" alt="" border=0 align=middle></a><br>
+      whose rendering automatically varies appropriately with font&nbsp;size.
+      This kind of <a href="#newcommands">\newcommand</a> construction
+      is the primary use intended for mimeTeX's expression evaluation feature.
+      </p>
+  <p> But mimeTeX also provides the <b>\eval{<i>expression</i>}</b>
+      command to make the expression evaluation feature render
+      &quot;visible&quot; results. It's not particularly useful,
+      but an expression like &nbsp; <b>1+2+3+4+5=\eval{1+2+3+4+5}</b> &nbsp;
+      renders &nbsp;
+       <a href="#preview"><img id="eval2" onclick="eqntext('eval2')"
+       src="../cgi-bin/mimetex.cgi?\small 1+2+3+4+5=\eval{1+2+3+4+5}"
+       alt="" border=0 align="bottom"></a>. </p>
+  <p> Finally, one little &quot;gotcha&quot; is mimeTeX's
+      order&nbsp;of&nbsp;evaluation when interpreting expressions.
+      Parentheses are respected as you'd expect. But within
+      &nbsp; <b>(</b>...<b>)</b> &nbsp; parentheses, or in an
+      unparenthesized expression, mimeTeX finds the first (reading
+      from the left) operator, then iteratively evaluates the
+      separate subexpressions to that operator's left and to its right,
+      and then finally combines those two separate results.
+      So an expression like <b>2*3+4</b>&nbsp;renders&nbsp;<b>14</b>,
+      and you need to write <b>(2*3)+4</b>&nbsp;to&nbsp;get&nbsp;<b>10</b>.
+      </p>
+ <h3> <a name="magstep"> \magstep{&nbsp;} &nbsp; and &nbsp;
+      \magbox{&nbsp;}{&nbsp;}<font size=5>...</font></a> </h3>
+  <p class="continue">
+      &nbsp;<b>\magstep{<i>magnification</i>}</b>, placed anywhere
+      within an expression, magnifies the entire expression
+      by an integer factor <b>1&lt;=<i>magnification</i>&lt;=10</b>
+      in both width and height.
+      Each single pixel thus becomes a square box, <i>e.g.</i>,
+      for <b><i>magnification</i>=2</b> each single pixel becomes
+      a four-pixel square box with dimensions&nbsp;<b>2</b>-by-<b>2</b>.
+      This compromises mimeTeX's anti-aliasing algorithm,
+      and the resulting image is both hazy/blurry and jagged/staircased
+      compared to an unmagnified image of the same expression.
+      For example, at <b>\LARGE</b> size,<br>
+       <nobr> &nbsp; &nbsp; &nbsp &nbsp;
+         <b>f(x)=x^2</b> &nbsp;
+         renders &nbsp;
+         <a href="#preview"><img id="magbox1" onclick="eqntext('magbox1')"
+         src="../cgi-bin/mimetex.cgi?\LARGE f(x)=x^2"
+         alt="" border=0 align="absmiddle"></a> &nbsp; and </nobr><br>
+       <nobr> &nbsp; &nbsp; &nbsp &nbsp;
+         <b>\magstep{2} f(x)=x^2</b> &nbsp;
+         renders &nbsp;
+         <a href="#preview"><img id="magbox2" onclick="eqntext('magbox2')"
+         src="../cgi-bin/mimetex.cgi?\LARGE\magstep{2} f(x)=x^2"
+         alt="" border=0 align="absmiddle"></a>&nbsp;, &nbsp; whereas </nobr><br>
+       at mimeTeX's largest &quot;native&quot; font&nbsp;size, <br>
+       <nobr> &nbsp; &nbsp; &nbsp &nbsp;
+         <b>\Huge f(x)=x^2</b> &nbsp;
+         renders &nbsp;

+         src="../cgi-bin/mimetex.cgi?\HUGE f(x)=x^2"
+         alt="" border=0 align="absmiddle"></a>&nbsp;. </nobr><br>
+      Nevertheless, if you still want to render images larger than
+      mimeTeX's <b>\Huge</b> size, then <b>\magstep{<i>magnification</i>}</b>
+      may render almost-acceptable results. </p>
+  <p> To magnify just part of an expression,
+      you can use <b>\magbox{<i>magnification</i>}{<i>expression</i>}</b>,
+      which only magnifies each pixel within the enclosed
+      <b>{<i>expression</i>}</b>, again
+      by an integer factor <b>1&lt;=<i>magnification</i>&lt;=10</b>
+      in both width and height, and also adjusts the baseline accordingly.
+      But <b>\magbox</b> is applied directly to mimeTeX's black-and-white
+      bitmap <u><b><i>&nbsp;before&nbsp;anti-aliasing&nbsp;</i></b></u>.
+      At the present time, this virtually completely defeats
+      mimeTeX's anti-aliasing algorithm, and the resulting image
+      exhibits even more pronounced jagged-line/staircase effects.
+      For example, <br>
+       <nobr> &nbsp; &nbsp; &nbsp &nbsp;
+         <b>\LARGE f(x)={\magbox{2}{x}}^2</b> &nbsp;
+         renders &nbsp;

+  <p> Any (La)TeX error is typically also a mimeTeX error.
+      However, mimeTeX has no command line interface or
+      <b>.</b>log file for reporting errors.  Its only
+      communication with you is through the mimeTeX image
+      rendered by your browser.  So error messages are embedded
+      in that image whenever feasible.  For example,
+      suppose you want to see
+       <a href="#preview"><img id="messages1" onclick="eqntext('messages1')"
+       src="../cgi-bin/mimetex.cgi?\normalsize\alpha\beta\gamma\delta"
+       border=0 align=bottom></a>, but you mistakenly type
+       &nbsp; <b>\alpha\bethe\gamma\delta</b> &nbsp; instead.
+      Then the image rendered is
+       <a href="#preview"><img id="messages2" onclick="eqntext('messages2')"
+       src="../cgi-bin/mimetex.cgi?\normalsize\alpha\bethe\gamma\delta"
+       border=0 align=bottom></a>, indicating the unrecognized
+      <b>[\bethe?]</b> where you wanted to type &nbsp; <b>\beta</b> &nbsp;
+      and hoped to see
+       <a href="#preview"><img id="messages3" onclick="eqntext('messages3')"
+       src="../cgi-bin/mimetex.cgi?\normalsize\bf\beta"
+       border=0 align=bottom></a>.
+      If your expression contains some unprintable character
+      (meaning any character mimeTeX has no bitmap for),
+      then just &nbsp;
+       <a href="#preview"><img id="messages4" onclick="eqntext('messages4')"
+       src="../cgi-bin/mimetex.cgi?\small\bf[?]"
+       border=0 align=bottom></a> &nbsp; is displayed in the
+      corresponding position. </p>
+  <p> The preceding example illustrates a pretty trivial error.
+      Any non-trivial errors in your expression are likely to
+      go unrecognized and unreported by mimeTeX, and to render
+      unexpected images.  While checking your input expression
+      for syntax errors, keep in mind the following points
+      about mimeTeX's behavior: </p>
+      <ul>
+        <li> An unmatched left brace &nbsp; <b>{</b> &nbsp; is matched
+             by mimeTeX with a "phantom" right brace &nbsp; <b>}</b> &nbsp;
+             that's imagined to be at the end of your expression. </li>
+        <li> Likewise, an unmatched &nbsp; <b>\left(</b>, &nbsp;
+             or <b>\left\{</b> &nbsp; or <b>\left\</b><i>anything</i>, &nbsp;
+             is matched by mimeTeX with a "phantom" &nbsp; <b>\right.</b>
+             &nbsp; at the end of your expression. </li>
+        <li> On the other hand, an unmatched right brace &nbsp; <b>}</b>
+             &nbsp; is displayed in place, as if you had typed \rbrace. </li>
+        <li> But an unmatched &nbsp; <b>\right\</b><i>anything</i> &nbsp;
+             is interpreted as an abbreviation for <b>\</b>rightarrow
+             followed by <b>\</b><i>anything</i>.  For example, &nbsp;
+             <b>\leff(&nbsp;abc&nbsp;\right)&nbsp;def</b> &nbsp; renders &nbsp;

+ <p> One small problem with the above procedure is that the default
+   &nbsp; gftype &nbsp; program supplied with most TeX distributions
+   can't emit the long lines needed to display mimeTeX's larger font sizes.
+   <a href="http://www.forkosh.com/gftype.zip"
+   target="_top">gftype.zip</a>&nbsp;contains a statically linked linux
+   executable modified to emit the necessary long lines.
+   It may or may not run on your intel linux machine.
+   If not, you'll need to compile your own version from source.
+   The following instructions are for Unix/Linux: <br> &nbsp; &nbsp;
+   &nbsp; &nbsp; First, download both
+   <!-- http://www.ctan.org/tex-archive/systems/web2c/web-7.5.3.tar.gz -->
+   <a href="http://www.forkosh.com/web-7.5.3.tar.gz"
+   target="_top">web-7.5.3.tar.gz</a> and
+   <!-- http://www.ctan.org/tex-archive/systems/web2c/web2c-7.5.3.tar.gz -->
+   <a href="http://www.forkosh.com/web2c-7.5.3.tar.gz"
+   target="_top">web2c-7.5.3.tar.gz</a>
+   <!-- or more recent versions. --> (note: these files are no longer
+   explicitly archived by&nbsp;<a href="http://www.ctan.org/"
+   target="_top">ctan</a>, having been superceded
+   by&nbsp;<a href="http://www.ctan.org/tex-archive/systems/texlive"
+   target="_top">texlive</a>&nbsp;sources, so the preceding two links
+   point to copies kept on my site, www.forkosh.com).
+   Then &nbsp; untar &nbsp; both gzipped tar files,
+   &nbsp; cd&nbsp;web2c-7.5.3/ &nbsp; and run &nbsp; ./configure &nbsp;
+   and &nbsp; make &nbsp; in the usual way (make may fail before
+   completion if you don't have all needed fonts installed,
+   but it will create and compile gftype.c before failing).  Now edit
+   &nbsp; texk/web2c/gftype.c&nbsp; and notice three lines very near the top
+   that &nbsp; #define&nbsp;maxrow&nbsp;(79) &nbsp and similarly for
+   maxcol and linelength. Change all three 79's to 1024, and
+   then re-run make. The new &nbsp; texk/web2c/gftype &nbsp; executable
+   image can emit the long lines needed for mimeTeX's larger font sizes. </p>
+ <p> Finally, the Unix/Linux bash shell script
+   <a href="http://www.forkosh.com/texfonts.sh"
+   target="_top">texfonts.sh</a> generates file &nbsp; texfonts.h &nbsp;
+   containing the information for all 72 mimeTeX fonts discussed above
+   (and, optionally, an extra 1200dpi cmr font used to test mimeTeX's
+   supersampling algorithm).  You'll need to understand and edit this
+   script to use it meaningfully.  But it helps automate mimeTeX's font
+   generation procedure in case you want to experiment with different
+   fonts.  (Note that metafont emits a complaint while generating the
+dpi rsfs font.  Just press &lt;CR&gt; and it completes
+   successfully.) </p>
