Perl6-Pugs

= Changes for 6.2.13 (r14402) - October 17, 2006
== Build System
* Perl 5 embedding is now enabled by default
** For Windows users, Perl 5.8.x is required
** Set the `PUGS_EMBED` environment variable to `noperl5` to disable this
* Prompting for Parrot embedding is now disabled by default
** Set the `PUGS_EMBED` environment variable to `parrot` to enable this
* Support for compiling using GHC 6.6
** GHC 6.4.1+ is still supported, but 6.6 will be required in the next release
== Feature Changes
=== Interactive Shell and Command-Line Flags
* New `pugs -d` flag to display a trace for debugging
* The `:r` command now resets the environment once, not twice
There are several environment variables that control pugs's build process.
You may use the GHC environment variable to set the ghc executable before
you run "perl Makefile.PL", for example:
export GHC=${HOME}/bin/ghc (bash)
setenv GHC ${HOME}/bin/ghc (csh)
To control which optional subsystems are embedded in Pugs, set the
PUGS_EMBED variable. For example:
export PUGS_EMBED="parrot noperl5" (bash)
setenv PUGS_EMBED "parrot noperl5" (csh)
Perl5 is now embedded by default. Use "noperl5" to disable.
To build with an embedded parrot interpreter, make sure the PUGS_EMBED
variable contains "parrot", and set the PARROT_PATH variable to point to
the directory in which you checked out the parrot source tree. For example:
export PARROT_PATH=${HOME}/src/parrot (bash)
setenv PARROT_PATH ${HOME}/src/parrot (csh)
MAKE TARGETS

subject: problem compiling UTF8 on Win32
summary: |-
A problem was reported with compiling UTF8 on Win32, but the same
poster discovered that `PUGS_EMBED` had been set tp 'perl5' and
removing the setting fixed the problem.
