Using import to read a DOS file and then mapping the records to a string array

Once you read a text file using
auto MyDictionary = import ("dictionary.txt");
how can you parse this into a string array stripping the CrLf
from the end of each line?
I suspect there is some variant of the split library function
that will parse it into a string array for me but because DOS
lines end with the CrLf which is 2 characters I'm not sure if
there is a way to do this with a one line call to a lib function.
And as I understand it with the import this file is read in at
compile time so after it has been parsed into the string array,
is there a way to free the storage that was used by the variable
MyDictionary.
I like this method because it minimizes the number of files I
have to distribute with my executable and prevents users from
modifying the files but I don't really want to keep 2 copies of
the data (imported and string array) in my program as the files
brought in will be quite large.
I realize I could just read it old school a record at a time but
that's usually slower and requires a bit more code.
Also if the files I am reading in have include references
#include filename are the any lib calls that can read in the main
file and expand the #include files as it reads.
