tds: The role of the TDS

 
 1.2 The role of the TDS
 =======================
 
 The role of the TDS is to stabilize the organization of TeX-related
 software packages that are installed and in use, possibly on multiple
 platforms simultaneously.
 
    At first glance, it may seem that the Comprehensive TeX Archive
 Network (CTAN) fulfills at least part of this role, but this is not the
 case.  The role of CTAN is to simplify archiving and distribution, not
 installation and use.
 
    In fact, the roles of the TDS and CTAN are frequently in conflict,
 as we will see.  For distribution, many different types of files must
 be combined into a single unit; for use, it is traditional to segregate
 files (even similar files) from a single package into separate,
 occasionally distant, directories.
