Initial Package Version: 2.54.0
Upstream Status: Not submitted
Origin: Self
Description: Adds a capabiility to skip printing warning messages using
an environment variable: GLIB_LOG_LEVEL. The value
of the variable is a digit that correponds to:
1 Alert
2 Critical
3 Error
4 Warning
5 Notice
For instance GLIB_LOG_LEVEL=4 will skip output of Warning and
Notice messages (and Info/Debug messages if they are turned on).
Rediffed for 2.68.0 to reduce the fuzz warnings.
