******               Installation of e-pTeX                     ******
----------------------------------------------------------------------

1. Prerequisites.
- GNU make and prereq. of TeX Live 2010
- perl
- GNU patch 
- GNU bash  (/bin/bash must be exist)
- xz-utils  (In particular, `xz' command)

Moreover, the followings are needed to execute ./reautoconf (executed in build.sh).
I am working with following versions:
- GNU autoconf 2.65
- GNU automake 1.11.1
- GNU m4       1.4.15
(autoconf >=2.66 may not work?)

2. Compile method.

Suppose that this file is located at $TLSRCDIR.

- Put the following files in $TLSRCDIR:
    texlive-20100720-source.tar.xz
  ## uptex_font-0.30.tar.gz
    freetype-2.4.2.tar.gz (if you use >=2.4.3, please change $FTVER in common.sh)

- Install TeX Live 2010.
  We denote the directory which TeX Live is installed by $TLINSTDIR.
- Edit common.sh.

$ ./all.sh -p -e -r
  The meaning of options can be showed using "./all.sh -h".
  ## If e-pTeX and upTeX will be compiled, also `e-upTeX' will be.
# scripts/install.sh

(optional) If ptex-qtrip-*.tar.gz is located at $TLSRCDIR,
you can perform TRIP, e-TRIP, and ``ptex-qtrip'' tests by script/trip.sh.
places of log files:
  $TMPDIR/texlive-20100720-source/Work/triptrap,
  $TMPDIR/texlive-20100720-source/Work/etrip,
  $TMPDIR/texlive-20100720-source/Work/ptex-qtrip.
