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 Waring and
|
|
Notice messages (and Info/Debug messages if they are turned on).
