-"By applying a post-processing filter to the Intermediate netlist file you can generate foreign netlist files as well as BOM files. Because this conversion is a text to text transformation, this post-processing filter can be written using *Python*, *XSLT*, or any other tool capable of taking XML as input.\n"
-"\n"
-"XSLT itself is a XML language suitable for XML transformations. There is a free program called `xsltproc` that you can download and install. The `xsltproc` program can be used to read the Intermediate XML netlist input file, apply a style-sheet to transform the input, and save the results in an output file. Use of `xsltproc` requires a style-sheet file using XSLT conventions. The full conversion process is handled by Eeschema, after it is configured once to run `xsltproc` in a specific way.\n"

-"A Python script is somewhat more easy to create.\n"

-"# 4 - Initialization of the dialog window\n"
-"\n"
-"You should add a new plugin (a script) in the plugin list by clicking on the Add Plugin button.\n"
-"\n"
-"## 4.1 - Plugin Configuration Parameters\n"
-"\n"
-"The Eeschema plug-in configuration dialog requires the following information:\n"
-"\n"
-" * The title: for instance, the name of the netlist format.\n"
-" * The command line to launch the converter (usually a script).\n"
-"\n"
-"***Note (Windows only):***\n"
-"*By default, the command line runs with hidden console window and output is redirected to \"Plugin info\" field. To show the window of the running command, set the checkbox \"Show console window\".*\n"
-"\n"
-"Once you click on the generate button the following will happen:\n"
-"\n"
-"1. Eeschema creates an intermediate netlist file \\*.xml, for instance `test.xml`.\n"
-"2. Eeschema runs the script from the command line to create the final output file.\n"
-"\n"
-"## 4.2 - Generate netlist files with the command line\n"
-"\n"
-"Assuming we are using the program `xsltproc.exe` to apply the sheet style to the intermediate file, `xsltproc.exe` is executed with the following command.\n"
-"\n"
-"```\n"
-"xsltproc.exe -o <output filename> <style-sheet filename> <input XML file to convert>\n"
-"```\n"
-"\n"
-"On Windows the command line is the following.\n"
-"\n"
-"```\n"
-"f:/kicad/bin/xsltproc.exe -o \"%O\" f:/kicad/bin/plugins/myconverter.xsl \"%I\"\n"
-"```\n"
-"\n"
-"On Linux the command becomes as following.\n"
-"\n"
-"```\n"
-"xsltproc -o \"%O\" /usr/local/kicad/bin/plugins/myconverter .xsl \"%I\"\n"
-"```\n"
-"where `myconverter.xsl` is the style-sheet that you are applying.\n"
-"\n"
-"Do not forget the double quotes around the file names, this allows them to have spaces after the substitution by Eeschema.\n"
-"\n"
-"If a Python script is used, the command line is something like (depending on the Python script):\n"
-"\n"
-"```\n"
-"python f:/kicad/bin/plugins/bom-in-python/myconverter.py \"%I\" \"%O\"\n"
-"```\n"

-"```\n"
-"python /usr/local/kicad/bin/plugins/bom-in-python/myconverter .xsl \"%I\" \"%O\"\n"
-"```\n"
-"\n"
-"The command line format accepts parameters for filenames. The supported formatting parameters are:\n"
-"\n"
-" * `%B`: base filename of selected output file, minus path and extension.\n"
-" * `%P`: project directory, without name and without trailing '/'.\n"
-" * `%I`: complete filename and path of the temporary input file\n"
-"(the intermediate net file).\n"
-" * `%O`: complete filename and path (but without extension) of the user\n"
-"chosen output file.\n"

-"`%B` will be replaced by the actual output short file name (the short root sheet filename minus extension).\n"
-"`%P` will be replaced by the actual current project path.\n"
-"\n"
-"## 4.3 - Command line format:\n"
-"\n"
-"### 4.3.1 - Remark:\n"
-"\n"
-"Most of time, the created file must have an extension, depending on its type.\n"
-"Therefore you have to add to the option ***%O*** the right file extension.\n"
-"\n"
-"For instance:\n"
-"\n"
-" * **%O.csv** to create a .csv file (comma separated value file).\n"
-" * **%O.htm** to create a .html file.\n"
-" * **%O.bom** to create a .bom file.\n"
-"\n"
-"### 4.3.2 Example for xsltproc:\n"
