+## build-all
+
+Build using all supported app.toml files.
+The "unsupported" app.toml files are those that are broken and should be
+fixed but do not currently impact our production work. They should be
+fixed.
+
+```
+    Usage: build-all [options] [args]
+      -c # Continue to next app.toml on build errors
+      -h # Help (this message)
+      -n # No action, just list app.toml files to process.
+      -r # Remove previous log files (rebuild everything)
+      -u # Attempt to build including unsupported app.toml files
+    Run "cargo xtask $args app.toml" for every available app.toml
+    $args defaults to "dist"
+```
