Create record name manifest during build

[David Bracey via Tech-talk <tech-talk at aps.anl.gov>]

Some of our IOC projects would like to use macro substitutions at their dbLoadRecords invocations in st.cmd:

    dbLoadRecords("${EPICS_IOCTOPS}/${IOCDIR}/db/MyRecords.db”, “P=XYZ”)

This means that the *.db files created by the build will have incompletely substituted record names after the build completes.

We have tooling that scrapes record names from the build-product *.db files, but the above would cause it to not see the final record names.

I would like to have the build create a manifest file that contains the fully substituted record names, basically by using grep, awk, etc. to parse the source db filename/path and the substitution tokens, and then call the perl script that does the substitutions, producing some file that is just a list of the fully substituted record names.

However, I don’t know how to make an EPICS Makefile do such an arbitrary thing.  

May I please get some guidance as to a smart way to do this?
