GRASS5.0: brief description of ASCII formats

This description of ASCII formats supported by GRASS5 is for quick reference only. For full up-to-date description see GRASS 5 Programmer's manual

Sites
```

Notes:
- sites data are stored in this ASCII format in GRASS database
- comment and header lines are optional
- elevation can be given as a 3rd dimension or an attribute
- read more about how to define time in GRASS: Programmer's Manual Chap. 23 Datetime library
- read more detailed description of sites format: GRASS 4.2(= 5.0) Site Record Format Specification
