+====== This page should include user experiences with the gEDA suite. ======
+===== Paul Csanyi's experiences =====
+Hello!
+My name is Paul Csanyi. I am a technics teacher in an elementary school.
+I use mainly Debian GNU/Linux operating system. I have installed the gEDA suite on my system.
+I am a newbe to the electronics and to the gEDA tools, but the electronics is so interesting theme to me so I decide to study gEDA tools and use it for making some simple projects. With these simple projects I intend to teach my pupils to fundamentals of electronics.
+I tried first the gEDA GUI, but then I red that it is better to use gEDA from the command line, so I did so.
+I have tried several times gEDA tools to make some simple projects. Up to the present I learn how to use gschem tool very easily.
+I made schematics easily.
+But then I need a symbol that I can't find in gschem library, so I decide to make it. I follow the tutorial
+[[http://wiki.geda-project.org/geda:tragesym_tutorial]] and ask some questions on the mailing list geda-user
+[[http://www.seul.org/cgi-bin/mailman/listinfo/geda-user]]. (The archive is not at this location anymore)
+Here in this Wiki I want to share some of mine experiences with the gEDA suite. I want to share some addons to the tragesym tutorial.
+If these thoughts are specific for the Debian system, like the place of the tragesym_template.gz file, then I shall write a note of this.
+I made a symbol for the 36-pin Centronics connector.
+From the "Tragesym tutorial":
+**Step1: Open a tragesym template file**
+  * open xterm window: eg.: urxvt
+  * cp /usr/share/doc/geda-doc/wiki/_media/tragesym_template.gz ~/gEDA/gaf/ \\
+__Note: This is Debian specific.__
+  * cd gEDA/gaf/
+  * gzip -d tragesym_template.gz
+  * Open in OpenOffice the tragesym_template file. I get OpenOffice Calc with opened file. "Set the type, style and position column to the most common value." I have saved this **tragesym_template** file for the future use.
+**Step2: Download the part data sheet and find the pin list**
+**Step3: Copy the pin list into an editor and prepare it**
+  *I have tried Midnight Commander as editor, but XEmacs is much better for this. I make Tabs between columns. From XEmacs I copy the lines into OpenOffice Calc.
+**Step4: Insert all missing data into the spreadsheet**
+  *In OpenOffice Calc I inserted all missing data. The label of the Pin 36 is 'IN SEL' and have a negation overbar, so I write in the approppriate column: \_IN\ SEL\_ Note that here is a space between 'IN' and 'SEL'. Maybe it is trivial, but if one have a space in the label this works.
+**Step5: Export the spreadsheet into a tab seperated text file**
+  *In OpenOffice I did File / Save As / Filename: tragesym_template-for_36-pin_centronics_connector / Filetype: Structural text (CSV) (.csv) / Filter setup: on / Save / Text boundary: empty
+**Step6: execute tragesym and create the symbol**
+  *tragesym tragesym_template-for_36-pin_centronics_connector 36-pin-centronics.sch
+**Step7: check the result with gschem and do some artwork**
+  *"Now we have a complete symbol."
+  *"You can copy the symbol to your local symbol library e.g. /usr/local/share/gEDA/sym/local/ and use it." \\
+cp 36-pin_centronics.sch /home/username/gEDA/gaf/gschem-sym/connectors/36-pin_centronics.sym
+This symbol can be viewed here: \\
+[[http://www.mediamax.com/paul_csanyi/Hosted/gschem_schems/36-pin-centronics.sym]] (dead link)
+In this symbol I put the footprint: "SUBD_FEMALE_LAY 25" but this is not the approppriate footprint for the 36-pin Centronics connector. I tried to find footprint for the 36-pin Centronics connector here:
+[[http://www.gedasymbols.org/]], but with no success.
+I think I gone to make one 36-pin Centronics footprint soon, using "PCB Footprint Guide" here:\\
