+<H3>txt2html - a text to HTML conversion tool
+</H3>
+<P><B>txt2html</B> is a simple tool for converting text files into HTML files.
+Text files can contain simple formatting and mark-up commands that
+<B>txt2html</B> converts into HTML.
+</P>
+<P><B>txt2html</B> was written by <A HREF = "http://www.cs.sandia.gov/~sjplimp">Steve Plimpton</A>. I use it for
+<A HREF = "http://www.cs.sandia.gov/~sjplimp/lammps.html">documentation</A> and <A HREF = "http://www.cs.sandia.gov/~sjplimp">WWW pages</A>. Anna Reese added the table
+formatting options.
+</P>
+<P>See the <A HREF = "example.txt">example.txt</A> and <A HREF = "example.html">example.html</A>
+files in the <B>txt2html</B> directory for examples of what all the
+formatting commands and mark-up syntax end up looking like in HTML.
+</P>
+
+
+
+
+
+
+<HR>
+
+<P><B>Syntax:</B>
+</P>
+<DL><DT>txt2html file
+<DD> read from text file, write HTML to standard output
+<DT>txt2html file1 file2 file3 ...
+<DD> read each argument as text file, write one HTML file per argument
+</DL>
+<P>Input files are first opened with the specified name. If that fails,
+a ".txt" suffix is added. Output files are created with an ".html"
+suffix, which is either added or replaces the ".txt" suffix.
+</P>
+<HR>
+
+<P><B>Compiling:</B>
+</P>
+<P>The source for <B>txt2html</B> is a single C++ file. Compile it by typing:
+</P>
+<PRE>g++ -o txt2html txt2html.cpp
+</PRE>
+<HR>
+
+<P><B>How the tool works:</B>
+</P>
+<P><B>txt2html</B> reads a text file, one <I>paragraph</I> at a time. A paragraph
+ends with:
+</P>
+<UL><LI> a blank line
+<LI> a line whose final word starts with ":" (a format string)
+<LI> the end of the file
+</UL>
+<P>Any line in the paragraph which ends with "\" is concatenated to the
+following line by removing the "\" character and following newline.
+This can be useful for some of the formatting commands described below
+that operate on individual lines in the paragraph.
+</P>
+<P>If a paragraph starts with a "<" character and ends with a ">"
+character, it is treated as raw HTML and is written directly into the
+output file.
+</P>
+<P>If a paragraph does not end with a format string, then it is
+surrounded with HTML paragraph markers (<P> and </P>),
+<A HREF = "#markup">mark-up</A> is performed, and the paragraph is written to the
+output file.
+</P>
+<P>If the paragraph ends with a format string, then <A HREF = "#format">formatting</A>
+is performed, <A HREF = "#markup">mark-up</A> is performed, and the paragraph is
+written to the output file.
+</P>
+<HR>
+
+<A NAME = "format"></A><B>Formatting:</B>
+
+<P>A format string is the last word of a paragraph if it starts with a
+":" character. A format string contains one or more comma-separated
+commands, like ":ulb,l" or ":c,h3". Note that a format string cannot
+contain spaces, else it would not be the last word. An individual
+command can have 0 or more arguments:
+</P>
+<UL><LI> <I>b</I> or <I>line()</I> = 0 arguments
+<LI> <I>image(file)</I> = 1 argument
+<LI> <I>link(alias,value)</I> = 2 or more comma-separated arguments
+</UL>
+<P>Format commands add HTML markers at the beginning or end of the
+paragraph and individual lines. Commands are processed in the order
+they appear in the format string. Thus if two commands add HTML
+markers to the beginning of the paragraph, the 2nd command's marker
+will appear 2nd. The reverse is true at the end of the paragraph; the
+2nd command's marker will appear 1st. Some comands, like <I>line</I> or
+<I>image</I> make most sense if used as stand-alone commands without an
+accompanying paragraph.
+</P>
+<P>Commands that format the entire paragraph:
+</P>
+<UL><LI> p --> surround the paragraph with <P> </P>
+<LI> b --> put <BR> at the end of the paragraph
+<LI> pre --> surround the paragraph with <PRE> </PRE>
+<LI> c --> surround the paragraph with <CENTER> </CENTER>
+<LI> h1,h2,h3,h4,h5,h6 --> surround the paragraph with <H1> </H1>, etc
+</UL>
+<P>Commands that format the lines of the paragraph as a list:
+</P>
+<UL><LI> ul --> surround the paragraph with <UL> </UL>, put <LI> at start of every line
+<LI> ol --> surround the paragraph with <OL> </OL>, put <LI> at start of every line
+<LI> dl --> surround the paragraph with <DL> </DL>, alternate <DT> and <DD> at start of every line
+</UL>
+<P>Commands that treat the paragraph as one entry in a list:
+</P>
+<UL><LI> l --> put <LI> at the beginning of the paragraph
+<LI> dt --> put <DT> at the beginning of the paragraph
+<LI> dd --> put <DD> at the beginning of the paragraph
+<LI> ulb --> put <UL> at the beginning of the paragraph
+<LI> ule --> put </UL> at the end of the paragraph
+<LI> olb --> put <OL> at the beginning of the paragraph
+<LI> ole --> put </OL> at the end of the paragraph
+<LI> dlb --> put <DL> at the beginning of the paragraph
+<LI> dle --> put </DL> at the end of the paragraph
+</UL>
+<P>Commands applied to each line of the paragraph:
+</P>
+<UL><LI> all(p) --> surround each line with <P> </P>
+<LI> all(c) --> surround each line with <CENTER> </CENTER>
+<LI> all(b) --> append a <BR> to each line
+<LI> all(l) --> prepend a <LI> to each line
+</UL>
+<P>Special commands (all HTML is inserted at beginning of paragraph):
+</P>
+<UL><LI> line --> insert a horizontal line = <HR>
+<LI> image(file) --> insert an image = <IMG SRC = "file">
+<LI> image(file,link) --> insert an image that when clicked on goes to link
+<LI> link(name) --> insert a named link that can be referred to elsewhere (see <A HREF = "#markup">mark-up</A>) = <A NAME = "name"></A>
+<LI> link(alias,value) --> define a link alias that can be used elsewhere in this file (see <A HREF = "#markup">mark-up</A>)
+</UL>
+<P>Table command:
+</P>
+<UL><LI> tb(c=3,b=5,w=100%,a=c) --> format the paragraph as a table
+</UL>
+<P>Arguments within tb() can appear in any order and are all optional,
+since they each have default values.
+</P>
+<UL><LI> c=N --> Make an N-column table. Treat the paragraph as one
+ long list of entries (separated by the separator character) and put
+ them into N columns one after the other. If N = 0, treat each line
+ of the paragraph as one row of the table with as many columns as
+ there are maximum entries in any line. Default is c=0.
+
+<LI> s=: --> Use the character string following the equal sign as
+ the separator between entries. Default separator is a comma "," which
+ you cannot specify directly since the comma delimits the tb() arguments
+
+<LI> b=N --> Create a border N pixels wide. If N is 0, there is no
+ border between or outside the cells. If N is 1, there is a minimal
+ border between and outside all cells. For N > 1, the border between
+ cells does not change but the outside border gets wider. Default is
+ b=1.
+
+<LI> w=N or w=N% --> The first form makes each cell of the table at
+ least N pixels wide. The second form makes the entire table take up
+ N% of the width of the browser window. Default is w=0 which means
+ each cell will be just as wide as the text it contains.
+
+<LI> a=X --> Align the entire table at the left, center, or right of the
+ browser window, for X = "l", "c", or "r". Default is a=c.
+
+<LI> ea=X --> Align the text in each entry at the left, center, or
+ right of its cell, for X = "l", "c", or "r". Default is browser's
+ default (typically left).
+
+<LI> eva=X --> Vertically align the text in each entry at the
+ top, middle, baseline, or bottom of its cell, for X = "t", "m", "ba",
+ or "bo". Default is browser's default (typically middle).
+
+<LI> cwM=N or cwM=N% --> The first form makes column M be at least
+ N pixels wide. The second form makes column M take up N% of the
+ width of the browser window. This setting overrides the "w"
+ argument for column M. Only one column per table can be tweaked
+ with this argument. Default is no settings for any column.
+
+<LI> caM=X --> Align the text in each entry of column M at the left,
+ center, or right of its cell, for X = "l", "c", or "r". This
+ setting overrides the "ea" argument for column M. Only one column
+ per table can be tweaked with this argument. Default is no settings
+ for any column.
+
+<LI> cvaM=X --> Vertically align the text in each entry of column m
+ at the top, middle, baseline, or bottom of its cell, for X = "t",
+ "m", "ba", or "bo". This setting overrides the "eva" argument for
+ column M. Only one column per table can be tweaked with this
+ argument. Default is no settings for any column.

+
+<A NAME = "markup"></A><B>Mark-up:</B>
+
+<P>The text of the paragraph is scanned for special mark-up characters
+which are converted into HTML.
+</P>
+<P>Bold and italic characters:
+</P>
+ <UL> <LI> "[" (left brace) --> turn-on bold by inserting a <B>
+ <LI> "]" (right brace) --> turn-off bold by inserting a </B>
+ <LI> "{" (left bracket) --> turn-on italics by inserting a <I>
+ <LI> "}" (right bracket) --> turn-off italics by
+ inserting a </I> </UL>
+
+<P>If a backspace '\' precedes any of the bold/italic mark-up characters,
+then mark-up is not performed; the mark-up character is simply left in
+the text.
+</P>
+<P>Links are inserted by enclosing a section of text in double quotes,
+and appending an underscore to the ending quote, followed by the link.
+The link ends when whitespace is found, except that trailing
+punctuation characters (comma, period, semi-colon, colon, question
+mark, exclamation point, parenthesis) are not considered part of the
+link.
+</P>
+<P> A link of the form "text"_link becomes <A HREF =
+"link">text</A> in the HTML output. The only exception is if
+"link" is defined elsewhere in the file as an alias (see the link
+command above). In that case, the value is used instead of the alias
+name. </P>
+
+<P>With these rules, links can take several forms.
+</P>
+<UL> <LI> "This links"_#abc to another part of this file which is
+labeled with a :link(abc) command. <BR>
+<LI> "This links"_other.html to another file named other.html. <BR>
+<LI> "This links"_other.html#abc to another file which has an "abc"
+location defined internally. <BR>
+<LI> "This links"_http://www.google.com to a WWW site. <BR>
+<LI> "This"_M12 could be used in place of any of the above forms. It
+requires an alias like :link(M12,http://www.google.com) to be defined
+elsewhere in the file. </UL>
