CPANPLUS::Internals::Source controls the updating of source files and

.PP
Functions exist to check if source files are still \f(CW\*(C`good to use\*(C'\fR as
well as update them, and then parse them.

.IX Subsection "$cb->_check_trees( [update_source => BOOL, path => PATH, verbose => BOOL] )"
Retrieve source files and return a boolean indicating whether or not
the source files are up to date.
.PP
Takes several arguments:
.IP "update_source" 4
.IX Item "update_source"
A flag to force re-fetching of the source files, even
if they are still up to date.
.IP "path" 4
.IX Item "path"
The absolute path to the directory holding the source files.
.IP "verbose" 4
.IX Item "verbose"
A boolean flag indicating whether or not to be verbose.
.PP
Will get information from the config file by default.
.ie n .Sh "$cb\fP\->_\|_check_uptodate( file => \f(CW$file\fP, name => \f(CW$name, [update_source => \s-1BOOL\s0, verbose => \s-1BOOL\s0] )"

.IX Subsection "$cb->__check_uptodate( file => $file, name => $name, [update_source => BOOL, verbose => BOOL] )"
\&\f(CW\*(C`_\|_check_uptodate\*(C'\fR checks if a given source file is still up-to-date
and if not, or when \f(CW\*(C`update_source\*(C'\fR is true, will re-fetch the source
file.
.PP
Takes the following arguments:
.IP "file" 4
.IX Item "file"
The source file to check.
.IP "name" 4
.IX Item "name"
The internal shortcut name for the source file (used for config
lookups).
