1 1.4 How 'tar' Archives are Named
1 ================================
1 
1 Conventionally, 'tar' archives are given names ending with '.tar'.  This
1 is not necessary for 'tar' to operate properly, but this manual follows
1 that convention in order to accustom readers to it and to make examples
1 more clear.
1 
1    Often, people refer to 'tar' archives as "'tar' files," and archive
1 members as "files" or "entries".  For people familiar with the operation
1 of 'tar', this causes no difficulty.  However, in this manual, we
1 consistently refer to "archives" and "archive members" to make learning
1 to use 'tar' easier for novice users.
