So OSS EPM like many open source projects is basically maintained by contributions of necessity. A gentleman who uses it extensively when through and spent maybe 20+ hours making it work for 13 and making it do what he needed for his use case. He felt it was worth his time to do the work and contribute it back. Even if he valued his time at minimum wage ($10 in Arizona) that is over $200. It is unlikely he works that cheap but if he did it would still be more than $75. I have put hundreds of hours in to open source projects without pay because to me it made sense. I use “free” products every day that represent thousands of hours so I see giving back as a good investment. You may wish to pay a developer to impliment what you want and contribute it back.
