From b12f175e63983b1248d0e3d3610b2f93f1f2d6d8 Mon Sep 17 00:00:00 2001 From: John Mulligan Date: Mon, 14 Nov 2022 10:57:25 -0500 Subject: [PATCH] src/script: add helper function has_build_dir This function returns successfully if $BUILD_DIR exists and is valid. This is a useful building block for automation around the build and can be used to avoid re-running commands that fail is the build dir exists already.
