-# awk script for converting an iCal formatted file to a sequence of org-mode headings.
-# this may not work in general but seems to work for day and timed events from Google's
-# calendar, which is really all I need right now...
-#
-# usage:
-#   awk -f THISFILE < icalinputfile.ics > orgmodeentries.org --assign NAME=category
-#
-# where the category is used to define a CATEGORY for all entries in
-# the file and also assign that label as a tag to each entry
-#
-# Note: change org meta information generated below for author and
-# email entries!
-#
-# Known bugs:
-# - not so much a bug as a possible assumption: date entries with no time
-#   specified are assumed to be independent of the time zone.
-#
-# Eric S Fraga
-# 20100629 - initial version
-# 20100708 - added end times to timed events
-#          - adjust times according to time zone information
-#          - fixed incorrect transfer for entries with ":" embedded within the text
-#          - added support for multi-line summary entries (which become headlines)
-# 20100709 - incorporated time zone identification
-#          - fixed processing of continuation lines as Google seems to
-#            have changed, in the last day, the number of spaces at
-#            the start of the line for each continuation...
-#          - remove backslashes used to protect commas in iCal text entries
-# no further revision log after this as the file was moved into a git
-# repository...
