#/ Usage: check-symbols.sh {check,build}

#/ Commands:
|
|
#/
|
|
#/ build - Update the *.sym files at the root of this repository
|
|
#/ based on the *.so files that have been built.
|
|
#/ check - Compare the *.sym files against the symbols exposed in
|
|
#/ the *.so files that have been built.
|
|
#/
|
|
#/ By checking in the *.sym files and running `check-symbols.sh check`
|
|
#/ in the gate, we establish an auditable record of when symbols are
|
|
#/ added or removed from the various *.so files we produce.
