The format of the replacements file is tab separated with three fields.
Any line that does not have a tab is ignored and can be considered a comment.
Fields are:
1. String to search for.
2. String to replace found text with.
3. (optional) The presence of this field indicates that the previous two
are considered a regular expression.
Example:
This is a comment
TARGET REPLACE
regex(p*) Count the Ps; \\1 true
