Install r4ge

To "install" it just create r2-macros in your .radare2rc file with the according path to the r4ge files. Requirements are of course angr and radare2 and also termcolor which is used for colored printing. main plugin file, performs static and dynamic analysis. mark a specific memory region as symbolic (addr: start address, bytes: how many bytes, name: name the variable). create hooks in r2 and patch function calls or other statements (syntax of the instructions: rax=0x4 or rax=0x4;rbx=0x10). create asserts to check register values during exploration (syntax of the instructions: rax==0x3 or rax#=0x3;rax<=0x10) Note: # is used instead of >, cause r2 uses > as pipe operator. it is also possible to search for a specific string in stdout, just call the makro below. this will ignore find flags, but will consider hooks and asserts. (r2 has many special characters so it may not be possible to put arbitrary strings in the makro but you can modify the r2-variable by your own). create an angr script out of the current r2 session. call a function and specifiy the return value (currently in development mode).
