Our coding style recommends C style comments (/* */) instead of C++ (//). Also, systemd (which we partly fork) uses C style comments for the SPDX-License-Identifier. Unify the style. $ sed -i '1 s#// SPDX-License-Identifier: \([^ ]\+\)$#/* SPDX-License-Identifier: \1 */#' -- $(git ls-files -- '*.[hc]' '*.[hc]pp')

|
* level because it uses libnm.

|
* Compile with:
