.Nd "create a random access file for storing strings"
57
reads a file containing groups of lines separated by a line containing
60
sign and creates a data file which contains
61
a header structure and a table of file offsets for each group of lines.
62
This allows random access of the strings.
64
The output file, if not specified on the command line, is named
65
.Ar source_file Ns Sy .out .
67
The options are as follows:
68
.Bl -tag -width "-c char"
70
Change the delimiting character from the percent sign to
73
Ignore case when ordering the strings.
75
Order the strings in alphabetical order.
76
The offset table will be sorted in the alphabetical order of the
77
groups of lines referenced.
78
Any initial non-alphanumeric characters are ignored.
79
This option causes the
85
Randomize access to the strings.
86
Entries in the offset table will be randomly ordered.
87
This option causes the

Run silently; don't give a summary message when finished.
95
Note that each alphabetic character in the groups of lines is rotated
96
13 positions in a simple caesar cypher.

The format of the header is:
107
u_int32_t str_version; /* version number */
108
u_int32_t str_numstr; /* # of strings in the file */

u_int32_t str_longlen; /* length of longest string */

All fields are written in network byte order. Each field is also
