#
# The common functions used by the s_winmsi scripts (both
# for core DB and DB/XML).
#
# This script uses several bash extensions that are convenient
# since we "know" it will always run under Cygwin: shell functions,
# 'return', declaration of 'local' variables, $(command) syntax,
# ${#X} (counting chars), ${X#regexp} (searching) $((expr)) (arithmetic)
#
# These functions use 'global' variables:
#   ERRORLOG             - a filename
#   PRODUCT_NAME         - e.g. "Berkeley DB"
#   PRODUCT_VERSION      - e.g. "4.1.25", derived from dist/RELEASE
#   PRODUCT_MAJOR        - e.g. "4", (for release 4.1.25) from dist/RELEASE
#   PRODUCT_MINOR        - e.g. "1", (for release 4.1.25) from dist/RELEASE
#   PRODUCT_PATCH        - e.g. "25", (for release 4.1.25) from dist/RELEASE
#   PRODUCT_MAJMIN       - e.g. "41", (for release 4.1.25) from dist/RELEASE
#   PRODUCT_MSVC_VERSION - e.g. "71" for Visual Studio 7, "80" for VS 8
#   PRODUCT_STAGE        - the staging directory for temp files and builds
#   PRODUCT_LICENSEDIR   - the tree containing LICENSE and README
#   PRODUCT_SUB_BLDDIR  - top of the subproduct build e.g. "dbxml-2.0.1/dbxml"
#   PRODUCT_BLDDIR       - top of the build tree e.g. "dbxml-2.0.1"
#   PRODUCT_SRCDIR       - the dir we unzip to e.g. "dbxml-2.0.1"
#   PRODUCT_DBBUILDDIR   - where build_unix dir is for Berkeley DB (for Perl)
#   PRODUCT_SHARED_WINMSIDIR   - where the master winmsi directory is
#   PRODUCT_IMAGEDIR     - where the images are (usually winmsi/images)
#   PRODUCT_ZIP_FILEFMT  - what zip file looks like e.g. "db-X.Y.Z.NC.zip"
#   PRODUCT_MSI_FILEFMT  - what msi file looks like e.g. "db-X.Y.Z.NC.msi"
#
# Some of these may seem redundant, but there are options to take
# an already built tree from a different place than where we'll unzip
# to and take our sources from, for example.  This allows a lot of flexibility
# for development and debugging (especially when these trees can be huge).
