We shouldn't always send these to stderr. (Among other things, the warning: prefix breaks the gitbuilder error detection.) Signed-off-by: Sage Weil <sage@inktank.com>

/*
|
|
* Ceph configuration file support.
|
|
*
|
|
* This class loads an INI-style configuration from a file or bufferlist, and
|
|
* holds it in memory. In general, an INI configuration file is composed of
|
|
* sections, which contain key/value pairs. You can put comments on the end of
|
|
* lines by using either a hash mark (#) or the semicolon (;).
|
|
*
|
|
* You can get information out of ConfFile by calling get_key or by examining
|
|
* individual sections.
|
|
*
|
|
* This class could be extended to support modifying configuration files and
|
|
* writing them back out without too much difficulty. Currently, this is not
|
|
* implemented, and the file is read-only.
