$ make

If you want to install the executable system wide in /usr/local/bin do the following (this is optional and requires root privlidges):

$ make install

install -o root -g root -m 0755 iroffer /usr/local/bin/iroffer

It is recomened that you copy the configuration file to another name so that you will have a reference to the defaults if something goes wrong.

$ cp sample.config mybot.config

Detailed information is available in the config file section of the documentation.

Note: As part of the configuration process, you will need to generate an encrypted password. To do this run iroffer with the "-c" flag.

$ ./iroffer -c

iroffer v1.3.b09 [20040823145936] by PMG
  Configuration File Password Generator

This will take a password of your choosing and encrypt it.
You should place the output this program generates in your config file.
You can then use your password you enter here over irc.

Your password must be between 5 and 8 characters
Please Enter Your Password: testtest
And Again for Verification: testtest

To use "testtest" as your password use the following in your config file:
adminpass cH0wSJcuWkuV.

When iroffer is started in foreground mode, you can monitor and interact with the program from your shell. It will allow you to issue admin commands. However you must stay logged in (or use a program such as screen) or iroffer will exit.

$ ./iroffer mybot.config
