## Detailed Description

class escape definition, used for sequential reading of archives

The class escape is used to insert escape sequences before each new file's data in an archive. The normal file's data is also rewritten if it contains such an escape sequence for it does not collide with real escape sequences At reading time, this class revert backs modification done to file's data containing escape sequences for they contain the original data. This class also provides the feature to skip to the next (real) escape sequence. This class inherits of generic files and its objects are to be used in a stack of generic file's objects. The object below contains modified data and escape sequences, the file over gets the normal file data and does never see escape sequences. Expected implementation is to have a compressor above an escape object and a sar or scrambler/blowfish/... object above it.
