###
### A library for shell scripts which creates reports in jUnit format.
### These reports can be used in Jenkins, or any other CI.
###
### Usage:
###     - Include this file in your shell script
###     - Use juLog to call your command any time you want to produce a new report
###        Usage:   juLog <options> command arguments
###           options:
###             -class="MyClass" : a class name which will be shown in the junit report
###             -name="TestName" : the test name which will be shown in the junit report
###             -error="RegExp"  : a regexp which sets the test as failure when the output matches it
###             -ierror="RegExp" : same as -error but case insensitive
###             -output="Path"   : path to output directory, defaults to "./results"
###     - Junit reports are left in the folder 'result' under the directory where the script is executed.
###     - Configure Jenkins to parse junit files from the generated folder
