#!/usr/bin/env bash
#
# This script requires an installed 'Iceberg'
#
# Usage:
#   ./create_lazarus_dmg.sh [chmhelp] [edit]
#
# This will setup a lazarus package in ~/tmp/buildlaz
# run 'freeze' of Iceberg and create the dmg.
#
# Options:
#   chmhelp          add package chmhelp and add chm,kwd files in docs/chm
#   append-revision  append svn revision to dmg
#
# To edit the Iceberg configuration 'lazarus.packproj', run
#   ./create_lazarus_dmg.sh edit
# This will create ~/tmp/buildlaz/lazarus.packproj. Open the file with Iceberg.
# When changed, save the file. Copy it back to the lazarus sources:
# cp ~/tmp/buildlaz/lazarus.packproj <lazarus>/tools/install/macosx/lazarus_release.packproj.template
#
# The script will replace the following in the lazarus.packproj:
#   _LAZVERSION_ with $LazVersion
#   _DATESTAMP_ with $DATESTAMP
#   18273645 with $LAZMAJORVERSION
#   45362718 with $LAZMINORVERSION
