Quickly creating a command line utility to run ASMifier (http://asm.ow2.org/asm40/javadoc/user/org/objectweb/asm/util/ASMifier.html).

asmifier.c

#include <stdio.h>
#include <errno.h>

int main(int argc, char* argv[]) {
    int i;
    char* argv2[argc+3];
    argv2[0] = "java";
    argv2[1] = "-cp";
    argv2[2] = argv[0];
    argv2[3] = "org.objectweb.asm.util.ASMifier";
    for (i = 1;i < argc; i ++) {
        argv2[i+3] = argv[i];
    }
    argv2[argc+3] = 0;
    execvp("java", argv2);
    printf("Cannot execute '");
    for (i = 0;i < argc+2; i ++) { printf("%s ", argv2[i]); }
    printf("', caused by error: %d\n", errno);
}

Stealing from Sam Pullara's idea for creating standalone executables from Java JAR files:

http://www.javarants.com/2004/01/07/standalone-java-programs-on-unix-systems-now-with-c-code/

I've modified it slightly to handle a JAR file that doesn't have a Main-Class entry in the manifest.
In my case, I'm feeding it the ASM "all" JAR so I can have a command line utility for running the 
org.objectweb.asm.util.ASMifier utility.

gcc asmifier.c
cat > asmifier a.out ~/.m2/repository/org/ow2/asm/asm-all/4.1/asm-all-4.1.jar
chmod +x asmifier
