v0.5.15

• Improved help messages Much better formatting
• Patched a bug in compilation on Ubuntu

v0.5.14

• Added -f option to polonius-editor
  The -f option allows the user to specify a FILE which contains our
  instruction sequences, rather than specifying those instructions
  via the command line.
  E.g.: polonius-editor ./text.txt -f ./instructions.txt
• Patched another bug found by the test suite in which Polonius
  couldn't handle blank lines in instruction sequences

v0.5.13

• Polonius can now accept single-line 'delimited' instructions
  Multiple instructions of the same type can now be given on a single
  line in the format: INSERT 0 abc; 10 def; 20 ghi
  Or: REPLACE 0 abc; 10 def; 20 ghi
  Or: REMOVE 0 2; 10 12; 20 22
  Literal semicolons can also be inserted by escaping the semicolon
  with a backslash, as in:
  INSERT 10 along the wall to keep\; and slept
• 'Instruction sets' have been renamed to the more appropriate
  'Instruction sequences'
  This gives a clearer idea of what they are
• Added loads more tests
• Patched another small bug found by the tests

v0.5.12

• Added infrastructure to run automated tests on changes to Polonius
  These will help to make sure that functionality isn't broken by any
  code changes.
• Patched a small bug in INSERT which was found by this new automated
  testing infrastructure

v0.5.11

• Use the program_name variable instead of hard-coding the name into
  error messages
• Make sure that the user provides instructions to execute
• Refuse to create a new file if the instruction sequence is invalid.
  If we're creating a new file, the first instruction should be an
  INSERT
• Immediately write a newline char when creating a new file

v0.5.10

• Emergency patch
  Patching a bug that I carelessly introduced earlier
  There's a reason that the current version number < 1
• Added more helpful error messages to invalid instruction errors

v0.5.9

• Moved from std::regex to boost::regex. This finally closes #29
• Removed unfinished cli build from make target 'all'

v0.5.8

• More sanity checks on block size inputs
  Block sizes are now stored as 64-bit integers, and there are more
  checks in place to ensure valid input. This closes #30
• Fixed problem with stack overflows in regex searches
  The standard library's regex search function is recursive and has
  potential to overflow the stack, particularly when searching very
  large documents (in fact the point of polonius) This was documented
  before it was fully understood in Github issue #29
  To fix it, polonius-reader is now compiled with -fsplit-stack.
  This option allows a discontiguous stack which grows automatically
  as needed

v0.5.7

Patched a bug with 'remove' instructions
Previously, remove instructions didn't work properly with the 'end'
keyword. That has now been fixed in this change. This closes #26

v0.5.6

Properly check whether given path is a directory
Added support for building outside of Debian
