* \brief main function for the pkgagent

* 1. Command Line Analysis :: test a rpm file from the command line
* 2. Agent Based Analysis :: run from the scheduler
*
* +-----------------------+
* | Command Line Analysis |
* +-----------------------+
*
* To analyze a rpm file from the command line:
* file :: if files are rpm package listed, display their meta data
* -v :: verbose (-vv = more verbose)
*
* example:
* $ ./pkgagent rpmfile
*
* +----------------------+
* | Agent Based Analysis |
* +----------------------+
*
* To run the pkgagent as an agent simply run with no command line args
* no file :: process data from the scheduler
* -i :: initialize the database, then exit
*
* example:
* $ upload_pk | ./pkgagent
*
* \param argc the number of command line arguments
* \param argv the command line arguments
* \return 0 on a successful program execution

/**
* @brief main function for the copyright agent
*
* The copyright agent is used to automatically locate copyright statements
* found in code.
*
* There are 3 ways to use the copyright agent:
* 1. Command Line Analysis :: test a file from the command line
* 2. Agent Based Analysis :: waits for commands from stdin
* 3. Accuracy Test :: tests the accuracy of the copyright agent
*
* +-----------------------+
* | Command Line Analysis |
* +-----------------------+
*
* To analyze a file from the command line:
* -C <filename> :: run copyright agent from command line
* -d :: turn on debugging information
* -T <Copyright Statements | URLs| Emails> :: Copyright Statements | URLs |Emails
*
* example:
* $ ./copyright -C myfiletoscan
*
* +----------------------+
* | Agent Based Analysis |
* +----------------------+
*
* To run the copyright agent as an agent simply run with no command line args
* -i :: initialize a connection to the database
* -d :: turn on debugging information
*
* example:
* $ upload_pk | ./copyright
*
* +---------------+
* | Accuracy Test |
* +---------------+
*
* To test the accuracy of the copyright agent run with a -t. Make sure to run the
* accuracy tests in the source directory with the testdata directory:
* -t :: run the accuracy analysis
*
* example:
* $ ./copyright -t
*
* Running the tests will create 3 files:
* 1. Matches: contains all of the matches found by the copyright agent, information
* includes what file the match was found in, the dictionary element
* that it matched, the name that it matched and the text that was found
* 2. False_Positives: contains all of the false positives found by the agent,
* information in the file includes the file the false positive was
* in, the dictionary match, the name match, and the text
* 3. Flase_Negatives: contains all of the false negatives found by the agent,
* information in the file includes the file the false negative was
* in, and the text of the false negative
*
* NOTE: -d will produces the exact same style of Matches file that the accuracy
* testing does. Currently this is the only thing that -d will produce
*
* @param argc the number of command line arguments
* @param argv the command line arguments
* @return 0 on a successful program execution
