    --| @SUMMARY Returns True iff the specified fragment matches the initial
    --| Fragment'Length characters of the In_String.
    --|
    function Begins_With (Fragment : String; In_String : String) return Boolean;

    --| @SUMMARY Returns True iff the specified fragment matches the last
    --| Fragment'Length characters of the In_String.
    --|
    function Ends_With (Fragment : String; In_String : String) return Boolean;

    --| @SUMMARY Returns True iff the specified fragment appears somewhere
    --| inside In_String.
    --|
    function Contains (Fragment : String; In_String : String) return Boolean;

    --| @SUMMARY Returns True iff the specified string is null or contains only
    --| blanks and tabs.
    --|
    function Is_Blank (This_String : in String) return Boolean;

    --| @SUMMARY Returns True iff the specified string contains no blanks
    --| or tabs.
    --|
    function Is_Continuous (This_String : in String) return Boolean;

    --| @SUMMARY Returns True iff the specified string has leading or trailing
    --| blanks or tabs.
    --|
    function Is_Padded (This_String : in String) return Boolean;

    --| @SUMMARY Returns a string stripped of all characters which match
    --| the specified character. For instance, if the character is ' ':
    --|
    --|      "This string contains spaces" => "Thisstringcontainsspaces"
    --|
    --| @SPECIAL_NOTES If "Ignore_Case" is True, both uppercase and lowercase
    --| characters which match the specified character will be stripped.

    --| @SUMMARY Returns a string stripped of all substrings which match
    --| the specified substring. For instance, if the substring is "in":
    --|
    --|      "This string contains spaces" => "This strg contas spaces"
    --|
    --| @SPECIAL_NOTES If "Ignore_Case" is True, both uppercase and lowercase

    --| is ' ' and the new character is '_':
    --|
    --|      "This string contains spaces" => "This_string_contains_spaces"
    --|

    --| @SUMMARY Returns a string with the indicated range replaced with
    --| the specified substring. The length of the range can be less than,
    --| equal to, or greater than the length of the substring.
    --|
    --| @SPECIAL_NOTES If the length of the range is < 0, the specified
    --| substring is inserted into the string starting at "From_Here",
    --| and no characters are removed from the existing string.

    --| @SUMMARY Returns a string with every occurrence of "Old_Substring"
    --| replaced by "New_Substring" (the two substrings need not be the same
    --| length). For instance, if the old substring is "in" and the new
    --| substring is "out":
    --|
    --|      "This string contains spaces" => This stroutng contaouts spaces"
    --|
    --| @SPECIAL_NOTES If "Ignore_Case" is True, both uppercase and lowercase
    --| characters which match the characters in the specified old substring
    --| will be replaced.
