+# rel.pth

+# This file and any other files contained in 
+# the same directory as prothon.exe that end in .pth,
+# are read by prothon.exe, the prothon interpreter, when
+# the interpreter starts running.
+
+# These .pth files may contain blank lines, comment lines that
+# start with #, lines that are valid directory paths, and prothon
+# import statements.
+
+# Directory paths are added to the list Sys.path.  Sys.path is used
+# by prothon when searching for packages and modules to load.  It
+# is searched in order through this list.
+
+# Import commands are executed as they are encountered in the .pth
+# file so make sure the needed path directories are specified first.
+
+# this period adds this prothon home directory to Sys.path
+.
+
+# this imports the File module
+# (which should probably be a built-in anyway)

+          a file, the interpreter will start an interactive console session when 
+          the main program finishes. More importantly, the variables will still

+          executing. The -t command line option starts a prothon file executing 
+          as a background thread. Here is the source code for a simple prothon 
+          program, tut3.pr, that just adds 1 to a global variable every second:</p>
+        <pre>C:\Prothon\pr\tutorial>prothon -t tut3.pr
+</pre>
+        <p>You can actually start many files executing with the -t option and

-        <p><a name="com"></a>When you have Prothon installed properly, you can 
-          start the interpreter in interactive console mode by simply typing &quot;prothon&quot; 
-          at the command prompt. Typing &quot;prothon -h&quot; will give you a 
-          summary of available command-line options.</p>
-        <pre>C:\>prothon

-Prothon 0.1 Interactive Console, Build 477, May 12 2004 (Ctrl-D to exit)
->>>
-</pre>
-        <p>As you can see from the console heading, you exit the interactive console by 
-          typing Control-D at the beginning of any line that starts with the normal 
-          &gt;&gt;&gt; prompt. You may have to hit enter a few times to get to 
-          this prompt.</p>
-        <p>In our tutorial we will use output from this console for most of the 
-          examples. You can follow along by typing the same things into your Prothon 
-          console. Even when large portions of code are loaded and run, this can 
-          be done by loading files into the console and we have provided such 
-          files for you to load and run with this tutorial.</p>
-        <p><a name="calculator"></a>Let's try something simple by using the console 
-          as a calculator:</p>
-        <pre>>>> 3**2 + 4**2
-25</pre>
-        <p>Two asterisks ( ** ) means &quot;raise to the power of&quot; so the 
-          formula I typed was &quot;3 squared plus 4 squared&quot; and the console 
-          echoed 25 (which we know is 5 squared). This shows the feature of the 
-          console that it echoes the value of whatever result is left on the last 
-          line typed.</p>
-        <p>You can also give commands. One that you will use often is the &quot;print&quot; 
-          command:</p>
-        <pre>>>> print "hello world"
-hello world</pre>
-        The print command prints whatever arguments follow it. In this case it 
-        is a simple string. This is a bit different than the last output of the 
-        console because we commanded the output instead of just letting the console 
-        default to showing us what value was left in the line. 
-        <p><a name="indent"></a>You can also type in statements that require multiple 
-          lines, such as the for statement:</p>
-        <pre>>>> for i in 3:
-...    print i
-...
-0
-1
-2</pre>
-        <p>Whenever you see the prompt with three dots "..." this means that the 
-          console is just storing up your input and not running it yet. It knew 
-          you weren't done yet after typing &quot;for i in 3:&quot; because the 
-          line ended in a colon ( : ). In Prothon, whenever a line ends in a colon, 
-          another line is expected to follow that is indented one level deeper 
-          than the current one. This is the beginning of a &quot;code block&quot;. 
-          All the lines that start at this indent level are run together as one 
-          block of code.</p>
-        <p>Note that the console tabs in one indent level whether you hit the 
-          tab key or the space key. It also goes back one whole indent level when 
-          you press backspace. When you are done entering a code block you must 
-          enter one blank line to let the console know the block is finished. 
-          Then Prothon runs the whole block of code at once. In this case it ran 
-          the for loop three times. We will discuss the for loop more later.</p>
-        <p><font face="Verdana, Arial, Helvetica, sans-serif" size="+2"><a name="eapf"></a>1.2 
-          Executing a Prothon File</font></p>
-        <p>Prothon source files are normal text files with any type of line endings 
-          (Unix, Windows, or Mac) that have file names ending in &quot;.pr&quot;. 
-          Prothon is an interpreter so you can run the Prothon source file directly 
-          without compiling it first. Just type &quot;prothon file.pr&quot; at 
-          the command prompt. Set your working directory to the prothon/pr/turotorial 
-          directory and try this:</p>
-        <pre>C:\prothon\pr\tutorial>prothon tut1.pr
-hello world
-</pre>
-        <p>This complex program should look familiar. The contents of the tut1.pr 
-          file is: </p>
-        <pre>print "hello world"</pre>
-        <p>You can see nothing special is needed in the source file. </p>
-        <p><a name="args"></a>Prothon programs can also have arguments. Just place 
-          them after the name of the .pr file as you would any normal program 
-          file:</p>
-        <pre>C:\prothon\pr\tutorial>prothon tut2.pr hello world "test 1 2 3"
-Argument: tut2.pr
-Argument: hello
-Argument: world
-Argument: test 1 2 3</pre> 
-        <p>The source code for tut2.pr is: </p>
-        <pre>for arg in Argv:
-	print "Argument:", arg
-</pre>
-        The arguments are placed in a Prothon list called Argv with the program 
-        name as the first item as is traditional. The for loop and lists will 
-        be described later.</td>
