53 * This program takes a file composed of strings separated by
54 * lines starting with two consecutive delimiting character (default
55 * character is '%') and creates another file which consists of a table
56 * describing the file (structure from "strfile.h"), a table of seek
57 * pointers to the start of the strings, and the strings, each terminated
58 * by a null byte. Usage:
60 * % strfile [-iorsx] [ -cC ] sourcefile [ datafile ]
62 * C - Allow comments marked by a double delimiter at line's beginning
63 * c - Change delimiting character from '%' to 'C'
64 * s - Silent. Give no summary of data processed at the end of
66 * o - order the strings in alphabetic order
67 * i - if ordering, ignore case
68 * r - randomize the order of the strings
71 * Ken Arnold Sept. 7, 1978 --
73 * Added ordering options.
