Subject: dpkg-gensymbols: override the check level with an environment variable
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0d0578a1a0d1287646e77739eead20841cf9a54;p=dpkg

dpkg-gensymbols: override the check level with an environment variable

* scripts/dpkg-gensymbols.pl: The environment variable
DPKG_GENSYMBOLS_CHECK_LEVEL can override the level of checks made by
dpkg-gensymbols. This offers the possibility to unofficial ports to ignore
errors due to symbols files that do not correspond.
