libeconf0 binary package in Ubuntu Noble amd64

 libeconf is a highly flexible and configureable library to parse and manage
 key=value configuration files. It reads configuration file snippets from
 different directories and builds the final configuration file for the
 application from it.
 .
 The first file is the vendor provided configuration file. There are two
 methods of overriding this vendor settings: copy the file from /usr/vendordir
 to /etc and modify the settings. Alternatively, a directory named
 file.suffix.d/ within /etc can be created, with drop-in files in the form
 name.suffix. This files contain only the changes of the specific settings the
 user is interested in. There can be several such drop-in files, they are
 processed in lexicographic order of their filename.
 .
 This package provides the library files needed at runtime.
