"<h2>What is FLUID?</h2>\n"
"The Fast Light User Interface Designer, or FLUID, is a graphical editor "
"that is used to produce FLTK source code. FLUID edits and saves its state "
"in <code>.fl</code> files. These files are text, and you can (with care) "
"edit them in a text editor, perhaps to get some special effects.<p>\n"
"FLUID can \"compile\" the <code>.fl</code> file into a <code>.cxx</code> "
"and a <code>.h</code> file. The <code>.cxx</code> file defines all the "
"objects from the <code>.fl</code> file and the <code>.h</code> file "
"declares all the global ones. FLUID also supports localization "
"(Internationalization) of label strings using message files and the GNU "
"gettext or POSIX catgets interfaces.<p>\n"
"A simple program can be made by putting all your code (including a <code>"
"main()</code> function) into the <code>.fl</code> file and thus making the "
"<code>.cxx</code> file a single source file to compile. Most programs are "
"more complex than this, so you write other <code>.cxx</code> files that "
"call the FLUID functions. These <code>.cxx</code> files must <code>"
"#include</code> the <code>.h</code> file or they can <code>#include</code> "
"the <code>.cxx</code> file so it still appears to be a single source file.<p>"
