                      7: ##   How can I get a list of all [[basics/make]] variables that are used by pkgsrc? 
                      8: 
                      9: 
                     10: That's difficult. But you can get a very good approximation by changing to a package directory and running the following command: 
                     11:     
                     12:     
                     13:     make -dv show-var VARNAME=VARNAME \
                     14:     | sed -n 's,^Global:\([^ ]*\) =.*,\1,p' \
                     15:     | sed 's,\..*,.*,' \
                     16:     | sort -u \
                     17:     | grep ^\[A-Z\] \
                     18:     | less
                     19:     
                     20: 
                     21: Another possibility is to run bmake show-all. This will list many (but not all) variables. 
                     22: 
                     23: If you need more information about a specific variable, run bmake help topic=_VARNAME_ or have a look at [pkglint's variable definition file](http://cvsweb.de.netbsd.org/cgi-bin/cvsweb.cgi/pkgsrc/pkgtools/pkglint/files/makevars.map?rev=HEAD)
                     24: 
                     25: 
                     26: ##   When patching a GNU-style configure script, where should I add changes? 
                     27: 
                     28: If you want your changes to override everything else, then look for "ac_config_files=" and put it somewhere before that line. 
                     29: 
                     30: ##   I'm going to make incompatible changes to pkgsrc. Where should I document it? 
                     31: 
                     32: In the file doc/CHANGES-*. 
                     33: 
                     34: ##   What's the difference between ${TEST}, test and [? 
                     35: 
                     36: There is practically no difference. All the standard options are supported on all platforms. See also [[pkgsrc/The pkgsrc portability guide#test]].
