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