Hi Frank,
For example, to connect different databases according to different requests, there are some options stored in a config file, like this:
[DB1] server=172.16.21.1 database=dbname1 userid=someone1 password=xxxxxx
[DB2] server=172.16.21.2 database=dbname2 userid=someone2 password=oooooo
i.e. with same key name in different sectors.
Yes, you'd just use the syntax above. The library would interpret the above as DB1.server=172.16.21.1 .... DB2.server=172.16.21.1 In other words, it would prepend the name of the section to the name of the option. For your use case, you might want to look at one of the examples: http://zigzag.lvk.cs.msu.su/~ghost/boost/libs/program_options/example/dynami... http://zigzag.lvk.cs.msu.su/~ghost/boost/libs/program_options/example/dynami... which unfortunately is not committed yet. - Volodya
