95}
96}

100This function returns the optional configuration file used for local customization

106if ($PBCONFVER < 1) {

108} else {
109    return("SSSS/pb.yml");
110}
111}
112
113
114=item B<pb_distro_init>
115
116This function returns a hash of parameters indicating the distribution name, version, family, type of build system, suffix of packages, update command line, installation command line and architecture of the underlying Linux distribution. The value of the fields may be "unknown" in case the function was unable to recognize on which distribution it is running.
117
118As an example, Ubuntu and Debian are in the same "du" family. As well as RedHat, RHEL, CentOS, fedora are on the same "rh" family.
119Mandriva, Open SuSE and Fedora have all the same "rpm" type of build system. Ubuntu and Debian have the same "deb" type of build system.
120And "fc" is the extension generated for all Fedora packages (Version will be added by pb).
121All this information is stored in an external configuration file typically at /etc/pb/pb.yml
122
123When passing the distribution name and version as parameters, the B<pb_distro_init> function returns the parameter of that distribution instead of the underlying one.
