| 21 | .SH DESCRIPTION
|
---|
| 22 | .B mg_fast_comp_dict
|
---|
| 23 | builds a fast-loading compression dictionary from the standard
|
---|
| 24 | compression dictionary. The new dictionary has the property that
|
---|
| 25 | .BR mgquery (1)
|
---|
| 26 | can load it in very quickly, making the startup time for
|
---|
| 27 | .BR mgquery (1)
|
---|
| 28 | much shorter. The new dictionary is larger on disk than the original,
|
---|
| 29 | but they are no different when it comes to memory usage.
|
---|
| 30 | .SH OPTIONS
|
---|
| 31 | Options may appear in any order.

| 32 | .TP "\w'\fB\-d\fP \fIdirectory\fP'u+2n"
|
---|
| 33 | .B \-h
|
---|
| 34 | This displays a usage line on
|
---|
| 35 | .IR stderr .
|
---|
| 36 | .TP
|
---|
| 37 | .BI \-d " directory"
|
---|
| 38 | This specifies the directory where the document collection can be found.
|
---|
| 39 | .TP
|
---|
| 40 | .BI \-f " name"
|
---|
| 41 | This specifies the base name of the document collection.
|
---|
| 42 | .SH ENVIRONMENT
|
---|
| 43 | .TP "\w'\fBMGDATA\fP'u+2n"
|
---|
| 44 | .SB MGDATA
|
---|
| 45 | If this environment variable exists, then its value is used as the
|
---|
| 46 | default directory where the
|
---|
| 47 | .BR mg (1)
|
---|
| 48 | collection files are. If this variable does not exist, then the
|
---|
| 49 | directory \*(lq\fB.\fP\*(rq is used by default. The command line
|
---|
| 50 | option
|
---|
| 51 | .BI \-d " directory"
|
---|
| 52 | overrides the directory in
|
---|
| 53 | .BR MGDATA .
