This program finds a given string in a batch of files and replaces them with ano
ther string and places the output files in a separate directory if such director
y is specified. The file size must be small enough to fit in available memory.

Command line parameters are:

-srcdir adirectory directory of the original files. By default, this is t
he current directory.

-destdir adirectory destination directory to save modified files. By defau
lt, this is the current directory. The source files will be over written.

-find atext find this text to replace.

-replace atext replace the text that was found with this one.

-fname apattern the file name pattern to search, for example *.*

-casesens presense of this flag means search is case sensitive.

-quotes this flag means the following characters are used instead of double quo
tes in the -find and -replace parameters. This is to help escaping quotes inside
your find replace parameters.
