+Mfile -  a simple Makefile generator for AVR-GCC
+================================================
+
+[See below for installation instructions]
+
+General
+-------
+
+The main purpose of this small application is to provide people an
+easy way to setup their project's Makefiles for »relatively standard«
+projects, so one could start using AVR-GCC without first studying the
+AVR's datasheet, plus the avr-libc documentation (really
+recommended!), /plus/ the »GNU make« user manual.
+
+It cannot really release the potential programmer from eventually
+studying the »GNU make« manual, but it can help to delay this part a
+few months.
+
+This generator works by using a Makefile template (the one that
+currently ships with WinAVR), load it into an editor buffer so the
+user can view the file and the changes, and then use a menu-driven
+approach to customize that buffer.  Eventually, at the user's
+discretion, this editor buffer can be saved into a Makefile.
+(Optionally, the user can also edit the buffer directly, so it acts as
+a simple text editor.)
+
+While the Programmer's Notepad 2 (PN2) editor that ships with WinAVR
+intends to eventually implement this functionality some day, there are
+two reasons for this little project:
+
+. Act as a stop-gap measure so users will get something they can use
+  right now, without waiting any longer.
+
+. Since this tool is written in Tcl/Tk, it is also portable to Unix
+  systems, so Unix users (who'd never benefit from PN2) might use it.
+
+I do explicitly /not/ intend to make this tool the all-singing
+all-dancing scriptable Makefile generator that can emit any Makefile
+for any processor and compiler on earth.  I really do not want to
+spend that many more hours into it, it was intented to be a quick and
+(hopefully not so) dirty tool that gets finished within a couple of
+evenings, and won't cost me another dozen of hours per months for
+supporting it, adding new features etc.  If you feel this is worth
+porting somewhere else (like for the MSP430-GCC that is probably
+fairly close to AVR-GCC in terms of typical use), please pick it up,
+extend it, and maintain it separately.  As always, I appreciate
+feedback, but reserve the right to ignore anything that tries to
+extend this tool above the outlined original purpose.
+
+Note that the Makefile template as shipped requires GNU make for
+various things (automagic dependency generation, some inference rules
+are written in gmake syntax as well).  However, as Mfile only relies
+on a few macro names in the template, it should be relatively easy to
+modify the template for other »make« dialects.  The template (or input
+file upon »File -> Open«) will be parsed when reading it, and only
+those features actually present will be displayed in the »Makefile«
+menu.  So if e. g. people don't want to include AVRdude features, they
+can delete all related lines from the template.  Also if someone (like
+Unix users, in particular those not using GNU make) want to modify the
+way the dependencies are generated (e. g. by using the traditional
+»make depend« approach), this should be completely unrelated.
+
+
+Prerequisites
+-------------
+
+Requires the Tcl and Tk toolkits in recent versions (no exact version
+known, probably any 8.x version is OK).  Current WinAVR (20030913)
+contains these tools.
+
+As an alternative to the standard Tk wish interpreter, the tix
+toolkit's tixwish interpreter can be used.  Under Unix systems, the
+look & feel is then closer to what Tk wish looks like under Windows.
+
+
+Installation on Windows
+-----------------------
+
+[Users of WinAVR 20040404 and beyond do get Mfile pre-installed.  See
+below for upgrade instructions.]
+
+Extract the archive into a subdirectory of its own, e. g.
+
+c:\WinAVR\mfile
+
+Double-click on the icon for »mfile.tcl« in your file browser
+(explorer), and tell it to use c:\WinAVR\bin\wish84.exe to run this
+file.  (Adjust appropriately if you installed WinAVR in another
+directory.)
+
+Since Windows always changes to the directory of the application
+before starting it, all template and auxiliary files should be found
+easily there without editing mfile.tcl.  Note however that this
+directory will also become the default directory where »Makefile« will
+be stored, unless you change a different location with »Save As...«
+
+As another option, the following has been contributed by Eric Weddington
+on how to properly create a shortcut on the desktop:
+
+1. Extract the mfile.zip archive into your WinAVR
+installation directory. This will automatically create a
+subdirectory \mfile with all the needed files in this
+subdirectory.
+
+2. Create a Shortcut on your Desktop.
+
+3. For the location of the item, select the program
+wish84.exe which is located in \bin subdirectory of your
+WinAVR installation directory. Add a space and then type
+the absolute pathname of the program, mfile.tcl, which is
+located in the mfile subdirectory of your WinAVR
+installation directory.
+
+For example, if your WinAVR installation directory is at
+C:\WinAVR, then the item will look like:
+C:\WinAVR\bin\wish84.exe C:\WinAVR\mfile\mfile.tcl
+
+4. The name of the Shortcut should be: MFile
+
+5. When finished, you will have to go back and properly
+select the Start Directory. Right-click the shortcut icon
+on your Deskopt and select Properties. In the Start In edit
+box, put in the mfile subdirectory of your WinAVR
+installation directory. NOTE! This is essential if MFile is
+to execute correctly as there are additional files that it
+needs to find.
+
+For example, if your WinAVR installation directory is at
+C:\WinAVR, then the Start directory will be:
+C:\WinAVR\mfile
+
+Installation on Unix
+--------------------
+
+Extract the archive into an arbitrary subdirectory, like
+
+/usr/local/share/mfile
+
+If a different directory is chosen, edit the setting of »prefix« on
+top of mfile.tcl to match the installation directory, or alternatively
+use the environment variable MFILE_HOME to override the default
+setting.
+
+If you'd like to use a different interpreter than
+/usr/local/bin/tixwish, edit the #! setting in the first line.  The
+standard Tk wish interpreter is supported as well as the tix toolkit
+one.
+
+If you prefer, create a symbolic link for convenience (so the
+application can be found along your default $PATH setting), like
+
+ln -s /usr/local/share/mfile/mfile.tcl /usr/local/bin/mfile
+
+Remember to edit the file makefile_template to suite your needs (e. g.
+default settings, adaptation to non-GNU make utilities).
+
+
+Upgrading an Mfile installation on WinAVR
+-----------------------------------------
+
+Starting with WinAVR 20040404, the WinAVR collection is shipping Mfile
+pre-installed.  (After all, the WinAVR users have once been the
+primary reason to develop Mfile at all.)
+
+In order to upgrade the Mfile files supplied with WinAVR, extract the
+archive into some directory, and copy all the files into
+
+<winavr directory>\mfile
+
+That ought to be all that is to be done.

+<h1>Simple Makefile generator for AVR-GCC</h1>
+<p>Copyright © 2003, 2004 Jörg Wunsch</p>
+
+<hr>
+<p>This simple Makefile generator is meant as an aid to quickly
+customize the WinAVR Makefile template, producing a file called
+<tt>Makefile</tt> in the current directory as result.</p>
+
+<p>The application consists of a (scrollable) text editor widget, and
+a menu bar.</p>
+
+<p>The <b>File</b> menu has only two entries:</p>
+
+<ul>
+  <li><b>Save</b> writes the contents of the text editor widget to a
+      file called <tt>Makefile</tt>.  Should any file by that name
+      already exist, it will be renamed.  Under Unix, a tilde will be
+      appended to the old name, all other platforms append a <tt>.bak</tt>
+      suffix.
+  <li><b>Save As</b> opens a filename selection dialog, and allows
+      the user to select a file to save to.  After selecting the file
+      name, it behaves identical to <b>Save</b>.
+  <li><b>Open</b> opens a filename selection dialog, requesting an
+      existing file to be opened by the user.  This file will be loaded
+      into the editor buffer, and the <b>Makefile</b> menu will be
+      updated accordingly.
+  <li><b>Exit</b> will quit the application.  No checks whatsoever
+      are done to ensure the user has saved his editing work before.
+</ul>
+
+<p>The <b>Makefile</b> menu allows customization of the generated
+Makefile.  Note that the various menu items described below will only
+be present if the corresponding feature is present in the parsed
+template or input file.  This menu is divided into three areas:</p>
+
+<ul>
+<li><b>Code generation options</b>
+<ul>
+  <li>The entry <b>Main file name</b> opens a popup window that asks
+      for the basic name of this
+      project.  This will become the base name for all major output files
+      (ELF file, MCU output file, several auxiliary files).  By default, it
+      will also serve as the name of the primary C source file, with a
+      <tt>.c</tt> suffix appended.  The popup will be closed by pressing
+      <i><Enter></i> in the entry field.
+  <li>The entries <b>MCU type</b>, <b>Output format</b>,
+      <b>Optimization level</b>,
+      and <b>C standard level</b> select possible values out of a
+      predefined list.  When selecting one of these options, the
+      respective Makefile macro will be modified accordingly, and the
+      widget will be adjusted so the new values can be seen
+      immediately.
+  <li>The entry <b>printf() options</b> works similar, only it does
+      not modify a Makefile macro of its own but edits the PRINTF_LIB
+      macro instead.  Note that setting this away from
+      <i>none/standard</i> will cause the generated application to
+      always include the code for vfprintf() (which is huge),
+      regardless of whether the application actually uses any member
+      of the printf() family.  See the avr-libc documentation for the
+      meaning of the different options.
+  <li>Likewise, changing the <b>scanf() options</b> changes the
+      macro SCANF_LIB, in the same manner.  Note that the
+      <tt>scanf()</tt> format %[ (string match out of a set of
+      characters) will only be present in the floating point version
+      since it requires a lot of code, as well as using
+      <tt>malloc()</tt> (which is otherwise only required for the
+      floating point version).
+  <li>The entry <b>C/C++ source file(s)</b> opens a popup that asks
+      for a list of C (or C++) source files.  C source files get the
+      suffix <tt>.c</tt> (lower-case letter c), C++ source files get
+      either of <tt>.C</tt> (capital c), <tt>.cxx</tt>, or <tt>.cc</tt>.
+      Multiple file names shall be seperated by spaces.  A checkbox
+      indicates whether the primary C source file name derived from
+      the <b>Main file name</b> setting should be included or not.
+      The popup will be closed by pressing <i><Enter></i> in the entry
+      field.
+  <li>The entry <b>Assembler source file(s)</b> works similar
+      except there are no default assembler sources to be included.
+      Note that assembler source files get the suffix <tt>.S</tt>
+      (capital letter s) which means they are being pre-processed by
+      the C preprocessor, so <tt>#include</tt> etc. will work.  A
+      lower-case letter <tt>.s</tt> suffix is considered to be a
+      temporary compiler output file, and should not be used here.
+  <li>Using <b>External RAM options</b>, several possible variants
+      to use external RAM can be selected.  This is internally handled
+      by editing the EXTMEMOPTS macro which eventually gets added to
+      the LDFLAGS during linking.  The options are to either use
+      external RAM for both, variables (i. e. sections .data and .bss)
+      as well as for the heap (dynamic memory for <tt>malloc()</tt>),
+      or to leave variables in internal memory and use the external
+      RAM only for the heap.  In both cases, the stack will always
+      remain in internal memory; this is the fastest way, and some
+      AVR MCUs have hardware bugs so they would not work when the
+      stack is located in external RAM.  It can be selected whether
+      the external RAM should start at the lowest possible memory
+      location (right behind the internal RAM), or at a different
+      memory address.  Several common memory sizes can be chosen from.
+      Obviously, these options are only accessible for MCU types that
+      do have an external memory interface.
+  <li>The entry <b>Debug format</b> selects one out of the following
+      options:
+      <ul>
+      <li><b>ELF/stabs</b> ELF object files with stabs debugging
+      information are currently the native way to debug under Unix
+      and/or GDB.  This includes any GDB frontend, like Insight or
+      DDD.
+      <li><b>AVR-COFF</b> Selecting this format will internally also
+      generate an ELF/stabs file, but change the Makefile to
+      subsequently convert the ELF file into a COFF file that adheres
+      to the originally Atmel AVR COFF file format specification.
+      This file format is understood by AVR Studio up to 3.x, and
+      VMLAB up to 3.9.
+      <li><b>AVR-ext-COFF</b> The conversion from internal ELF to
+      COFF will be tuned to produce a file according to the later
+      AVR "extended" COFF specification by Atmel, understood by AVR
+      Studio 4.07 and above, and VMLAB 3.10 and above.
+      <li><b>ELF/DWARF-2</b> Create an ELF standard object file with
+      DWARF-2 debug information.  This is the proposed standard debug
+      format for ELF.  It is currently Beta, the GNU tools are slowly
+      changing towards that standard (though it is not yet known
+      whether AVR-GDB will already fully understand the format yet),
+      and Atmel has released a beta ELF/DWARF-2 parser for their AVR
+      Studio.
+      </ul>
+</ul>
+<li><b>AVRdude options</b>
+<ul>
+  <li>The entry <b>Programmer</b> allows the selection of
+      the programming hardware (parallel port "dongle", or serially
+      connected hardware).
+  <li>The entry <b>Port</b> selects the serial or parallel
+      port AVRdude is going to talk across.  This menu item might
+      be missing on some operating systems where no default ports
+      are known.
+</ul>
+<li><b>Miscellaneous</b>
+<ul>
+  <li>By default, the editor widget is read-only, and can only be
+      modified by the menu entries mentioned above.  By checking the
+      <b>Enable Editing of Makefile</b> checkbox, this restriction can be lifted,
+      and the widget can be used as a simple standard text editor for
+      the generated Makefile.  Note that the menu operations mentioned
+      above are not guaranteed to work on arbitrary input texts since
+      they search for certain patterns in order to implement their
+      functionality, so manual editing should always be used as a last
+      step before eventually saving the generated Makefile.
+</ul>
+</ul>
