Hi Mike, sorry for the delay. It seems you did not see my post http://gis.19327.n8.nabble.com/Need-help-with-build-scripts-tt5957298.html where I attached a modified version of the buildoptions program. I've merged your changes with my patch, but omitted the part starting with "Input files may be of the following types: ". The list is incomplete. I think the program understands various compressed formats like *.osm.bz2 or *.osm.gz or *.osm.zip. Also missing is the polish format *.mp. We have a file resources\help\en\inputs. I think this would be the best place to put these details, but the link in file help is missing. I am not sure where to put your program and what licence /copyright message to use. This patch places it in src\buildoptions\OptionsBuilder.java because that made it easier for me to use it. Compared to my first patch I've modified the build script so that options is not automatically overwritten, instead one has to use ant options-file to "compile" it.

Februar 2020 12:44 An: 'Development list for mkgmap' Betreff: [mkgmap-dev] Minor documentation update Hi Gerd, now that my previous documentation patch has been committed, I have noticed a couple of errors in it that I didn't notice because I didn't have the means to compile it into the web pages. Please find attached a small patch that corrects these errors and adds some information on the input files, primarily to describe typ file compilation. I have also slightly tweaked the code for generating the options file from options.txt, but as the previous version does not appear to be in SVN, this has come across as a complete file, rather than the change (which is just the deletion of the hyphen character in 'if (line.startsWith(";-")) {').
