// ### This method should do the real building of the object,

// ### Typical situations include:
// ### - Initial building of an object from a few user-specified options
// ### - Building of a "reloaded" object: i.e. from the complete set of
// ### all serialised options.
// ### - Updating or "re-building" of an object after a few "tuning"
// ### options have been modified.
// ### You should assume that the parent class' build_() has already been
// ### called.
// ### In a SourceVMatrix, you will typically end build_() with:
// setMetaInfoFromSource();
// ### You should keep the line 'updateMtime(0);' if you do not implement
// ### the update of the mtime. Otherwise you can have an mtime != 0 that
// ### is not valid.
// ### Note that setMetaInfoFromSource() updates the mtime to the same as
// ### the source, but this value will be erased with 'updateMtime(0)'.
