The __frontend variable was introduced to address the needs of alterator-mkimage module: list the images available in one column, purge the builddir. Looks like we should consider other cases with redirected stdout (cron builds, piped calls, etc) like fundamentally non-interactive and behave the same. So commit 3a8af6b55d888d25c1d97561ed2ecf37ff28ad71's description is wrong now; the current cleanup rules are: - if CLEAN=0 or DEBUG>1, don't do it; - if CHECK or REPORT is set, don't do it; - otherwise if at least one of the following conditions is true: + there's more than one target being built in a row; + stdout was redirected (cronjob, alterator-mkimage...); + metaprofile directory is read-only ...then do a distclean. If that doesn't suit your needs, describe the particular situation please. Thanks cas@ for wondering aloud whether greppable output is unsupported with `make help'.
