    Introduction
    This vignette gives a short introduction to text mining in R utilizing the text mining framework provided by
    the tm package. We present methods for data import, corpus handling, preprocessing, metadata management,
    and creation of term-document matrices. Our focus is on the main aspects of getting started with text mining
    in R--an in-depth description of the text mining infrastructure offered by tm was published in the Journal of
    Statistical Software (Feinerer et al., 2008). An introductory article on text mining in R was published in R
    News (Feinerer, 2008).
    
    Data Import
    The main structure for managing documents in tm is a so-called Corpus, representing a collection of text
    documents. A corpus is an abstract concept, and there can exist several implementations in parallel. The
    default implementation is the so-called VCorpus (short for Volatile Corpus)
