.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
None of he following functions is exported by default.
.IP "apt_cache" 4
.IX Item "apt_cache"
Evaluate the creation of an AptPkg::Cache, and return it on success
.IP "find_cpan_module" 4
.IX Item "find_cpan_module"
Returns CPAN::Module object that corresponds to the supplied argument. Returns
undef if no module is found by \s-1CPAN.\s0
.Sp
If the \s-1CPAN\s0 module needs to be configured in some way, that should be done
before calling this function.
.IP "find_cpan_distribution" 4
.IX Item "find_cpan_distribution"
Returns CPAN::Distribution object that corresponds to the supplied argument.
Returns undef if no distribution is found by \s-1CPAN.\s0
.Sp
If the \s-1CPAN\s0 module needs to be configured in some way, that should be done
before calling this function.
.IP "is_core_module \fImodule\fR, \fIversion\fR" 4
.IX Item "is_core_module module, version"
Returns the version of the \f(CW\*(C`perl\*(C'\fR package containing the given \fImodule\fR (at
least version \fIversion\fR).
.Sp
Returns \f(CW\*(C`undef\*(C'\fR if \fImodule\fR is not a core module (anymore) in the current
\&\f(CW\*(C`perl\*(C'\fR release.
.IP "nice_perl_ver \fIversion_string\fR" 4
.IX Item "nice_perl_ver version_string"
Re-formats perl version to match Debian's perl package versions.
.Sp
For example \f(CW5.010\fR (and \f(CW5.01\fR) is converted to \f(CW5.10\fR.
.IP "core_module_perls \fImodule\fR[, \fImin-version\fR]" 4
.IX Item "core_module_perls module[, min-version]"
Returns a list of Perl versions that have \fImodule\fR. If \fImin-version\fR is
given, the list contains only Perl versions containing \fImodule\fR at least
version \fImin-version\fR.
.ie n .IP "find_core_perl_dependency( $module[, $version] )" 4
.el .IP "find_core_perl_dependency( \f(CW$module\fR[, \f(CW$version\fR] )" 4
.IX Item "find_core_perl_dependency( $module[, $version] )"
return a dependency on perl containing the required module version. If the
module is not available in any perl released by Debian, , or if it is not in
the current perl anymore, return undef.
.IP "split_version_relation \fIstring\fR" 4
.IX Item "split_version_relation string"
Splits the string, typically found in dependency fields' values in \s-1CPAN META\s0
into relation and version. If no relation is found in the string, \f(CW\*(C`>=\*(C'\fR is
assumed.
.Sp
Returns a list of relation and version. The relation is suitable for using in
Debian package dependency version requirements.
