This program was written out of a real-life need to modify PDF forms quickly, inexpensively and without Java. Don't get me wrong, I like Java, but I also like command line utilities, which is in the best traditions of Unix/Linux. The program is still in alpha and needs thorough testing. If you're interested in joining this small project to expand its capabilities, be sure to let me know.
Versions 1.2, 1.3 and 1.4 of the PDF specification should be supported but I only tried the utility on 1.3 and 1.4. Compression/decompression is handled through zlib. No encryption/decryption is supported because I first need to do some research on what the legal aspects of using the algorithms are. The parser and lexer are bison- and flex-based. The field types currently supported are checkboxes, radio buttons and text fields.
You can download the Linux version of acroformtool here.
