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