 # twic_script
 A bash script to maintain an update SCID database of chess games downloaded from The Week In Chess (TWIC) 
+
+==============================
+
+  This simple bash script helps maintaining an updated database of
+  chess games for SCID, based on the famous "The Week In Chess" game
+  collection made available at
+   
+  http://www.theweekinchess.com/
+ 
+  Games are distributed as zipped png files, which are uploaded weekly
+  on http://www.theweekinchess.com/zips/ (Should that URL change at some 
+  point in the future, you will just need to update the ADDR variable 
+  below)
+
+  *SYNOPSIS*
+     ./twic_script.sh --help
+     ./twic_script.sh [<start_issue> [<end_issue> [<pgnfile>]]]
+  
+  When called with "--help" as first argument, the script outputs
+  a *minimal* help.
+
+  Otherwise, if called with a start_issue (an integer, default to the 
+  first issue to be downloaded, as specified into ${IDFILE}, or to 
+  the first known online issue of TWIC, number 210, if ${IDFILE} does
+  not exist), it will start downloading the TWIC issues from start_issue
+  up to the latest (or up to end_issue, if provided). The zips are stored 
+  into ${ZIPDIR} (default to "./zips"), while the png database is 
+  maintained into ${PNGFILE} (default to ${DBDIR}/twic.png), or into the 
+  file provided by the user as third argument. 
+
+  The new pgn files are concatenated at the end of ${PNGFILE}, and then the
+  SCID database is rebuilt (this can take a while...).
+
+  The script maintains a record of the last downloaded issue, into the
+  file ${IDFILE} (default to ${ZIPDIR}/.last_id), so that it is sufficient
+  to call it regularly (e.g., as a user cron job) with no arguments in order
+  to have an updated DB of chess games. 
+
+  *DEPENDENCIES*
+  
+  twic_script.sh depends on:
+  
+  - wget (to download the zip files)
+  - unzip (well, what do you think we are using it for?)
+  - pgnscid (a program provided by scid to convert a pgn file into a SCID
+             .si4 game DB)
+
+  **** IMPORTANT NOTE ****
+ 
+  BEWARE!!! IF YOU REMOVE ${PNGFILE}, THE CORRESPONDING SCID DB FILE WILL 
+  BE OVERWRITTEN BY THE FIRST RUN OF THIS SCRIPT!!!
