i replaced the option parser with cxxopts, it should have the interface now on all platforms.

• the option flags changed a bit.
  • the project path needs now the p flag instead of appending it at the end (i havent found a way to do it without a flag).
  • platforms is now -s or --platforms
• options containing more than one word need to be wrapped in double quotes

#!/bin/sh cd "$(dirname "$0")" PG=./bin/projectGenerator.app/Contents/MacOS/projectGenerator OF=/Users/thomas.geissl/libs/of_v0.11.0_osx_release/ $PG -h $PG --help $PG -l -o $OF mkdir test $PG -o $OF -p test/first $PG -o ../../.. -p test/second -a ofxOsc,ofOpenCv $PG -o ../../.. -p test/second -a "ofxOsc, ofxOpenCv, ofxSvg" $PG -o ../../.. -p test/second -a "ofxOsc, ofxOpenCv, ofxSvg" -s osx -v $PG -o ../../.. -p test -r -d -v PG_OF_PATH=../../.. $PG -p test/third -a "ofxOsc, ofxOpenCv, ofxSvg" -t nofmod 

the version flag is still missing, but in case you wanna merge this, i think it is important to first merge my other pr #242 and tag it.
then this would be already a new major release.

i only tested on osx.

let me know what you think, anything i should improve?

i totally forget the frontend, will do the changes this week.

turned out that the cli readme is outdated and the option parser works already the same on all platforms.

i still think it makes sense to replace it with another more intiutive option parser.
#243

I think this is a good change. But we have to change the way it handle parameters right? like -o"../../.." needs a space between -o and value ?
