+# Makes a zip file of the most recent files in a specified directory.
+# By Rudi Farkas, rudif@bluemail.ch, 9 December 2000
+# Usage:
+# ziprecent <dir> -d <ageDays> [-e <ext> ...]> [-h] [-msvc] [-q] [<zippath>]
+# Zips files in source directory and its subdirectories
+# whose file extension is in specified extensions (default: any extension).
+# -d <days> max age (days) for files to be zipped (default: 1 day)
+# <dir> source directory
+# -e <ext> one or more space-separated extensions
+# -h print help text and exit
+# -msvc may be given instead of -e and will zip all msvc source files
+# -q query only (list files but don't zip)
+# <zippath>.zip path to zipfile to be created (or updated if it exists)

+
+=head1 SYNOPSIS
+
+ ziprecent h:/myperl
+
+ ziprecent h:/myperl -e pl pm -d 365
+
+ ziprecent h:/myperl -q
+
+ ziprecent h:/myperl h:/temp/zip/file1.zip
+
+
+=head1 DESCRIPTION
+
+This script helps to collect recently modified files in a source directory
+into a zip file (new or existing).
+
+It uses Archive::Zip.
+
+=over 4
+
+=item C< ziprecent h:/myperl >
+
+Lists and zips all files more recent than 1 day (24 hours)
+in directory h:/myperl and it's subdirectories,
+and places the zip file into default zip directory.
+The generated zip file name is based on local time (e.g. 20001208-231237.zip).
+
+
+=item C< ziprecent h:/myperl -e pl pm -d 365 >
+
+Zips only .pl and .pm files more recent than one year.
+
+
+=item C< ziprecent h:/myperl -msvc >
+
+Zips source files found in a typical MSVC project.
+
+
+=item C< ziprecent h:/myperl -q >
+
+Lists files that should be zipped.
+
+
+=item C< ziprecent h:/myperl h:/temp/zip/file1.zip >
+
+Updates file named h:/temp/zip/file1.zip
+(overwrites an existing file if writable).
+
+
+=item C< ziprecent -h >
+
+Prints the help text and exits.
+
+ ziprecent.pl <dir> -d <days> [-e <ext> ...]> [-h] [-msvc] [-q] [<zippath>]
+ Zips files in source directory and its subdirectories
+ whose file extension is in specified extensions (default: any extension).
+ -d <days> max age (days) for files to be zipped (default: 1 day)
+ <dir> source directory
+ -e <ext> one or more space-separated extensions
+ -h print help text and exit
+ -msvc may be given instead of -e and will zip all msvc source files
+ -q query only (list files but don't zip)
+ <zippath>.zip path to zipfile to be created (or updated if it exists)
+
+=back
+
+
+=head1 BUGS
+
+Tested only on Win2k.
+
+Does not handle filenames without extension.
+
+Does not accept more than one source directory (workaround: invoke separately
+for each directory, specifying the same zip file).
