Publications (and donations) tracer
duecredit is being conceived to address the problem of inadequate citation of scientific software and methods, and limited visibility of donation requests for open-source software.
It provides a simple framework (at the moment for Python only) to embed publication or other references in the original code so they are automatically collected and reported to the user at the necessary level of reference detail, i.e. only references for actually used functionality will be presented back if software provides multiple citeable implementations.
To get a sense of what duecredit is about, run for example shipped along example script, or your analysis script with -m duecredit, e.g.
python -m duecredit examples/example_scipy.py
