- Glimpse (which stands for GLobal IMPlicit SEarch) is an indexing and
- query system that allows you to search through all your files very
- quickly. For example, finding 296 lines containing 'whitehouse' in 8750
- files occupying 104MB took 6 seconds on a SUN Sparc 5. Glimpse supports
- most of agrep's options (agrep is our powerful version of grep)
- including approximate matching (e.g., finding misspelled words), Boolean
- queries, and even some limited forms of regular expressions. It is used
- in the same way, except that you don't have to specify file names. So,
- if you are looking for a needle anywhere in your file system, all you
- have to do is say glimpse needle and all lines containing needle will
- appear preceded by the file name.
