how do I tell cutplace about this check class
<p>I am trying to use the API in cutplace to build a custom check
<a href="http://cutplace.sourceforge.net/api.html#writing-checks" rel="nofollow">http://cutplace.sourceforge.net/api.html#writing-checks</a></p>

<p>Using the included demo data and code I have tried to follow the manual, at least until it ends abruptly.</p>

<p>useCutplace.py:</p>

<pre><code># Validate a test CSV file.
import os.path
from cutplace import interface
from cutplace import checks
from cutplace import ranges

class FullNameLengthIsInRangeCheck(checks.AbstractCheck):
    """Check that total length of customer name is within the specified range."""
    def __init__(self, description, rule, availableFieldNames, location=None):
        super(FullNameLengthIsInRangeCheck, self).__init__(description, rule, availableFieldNames, location)
        self._fullNameRange = ranges.Range(rule)
        self.reset()
def checkRow(self, rowMap, location):
    fullName = rowMap["last_name"] + ", " + rowMap["first_name"]
    fullNameLength = len(fullName)
    try:
        self._fullNameRange.validate("full name", fullNameLength)
    except ranges.RangeValueError, error:
        raise CheckError("full name length is %d but must be in range %s: %r" \
                % (fullNameLength, self._fullNameRange, fullName))

icdPath = os.path.join("icd_customers_field_names_only.csv")
dataPath = os.path.join("customers.csv")
icd = interface.InterfaceControlDocument()
icd.read(icdPath)
for row in interface.validatedRows(icd, dataPath):
    print row
</code></pre>
